MICRO-Joe's Boots uses a job-order costing system

Joe's Boots uses a job-order costing system and applies manufacturing overhead cost to boots using direct labor hours. The predetermined overhead application rate was based on a formula that estimates

\$ 788,000

of total manufacturing overhead for an estimated activity level of 20,000 direct labor hours. Joe's year-end records include the following: Direct labor hours are 20,000 Manufacturing overhead cost of

\$ 761,000

. Calculate the over(under)application of manufacturing overhead. Provide overapplication as a positive value, and underapplication as a negative. Round your answer to 2 d.p. Do not round intermediary calculations.

Answer

-$27,000.00

Solution

a

Predetermined Overhead Rate Calculation: The predetermined overhead rate is calculated based on the estimated total manufacturing overhead and the estimated activity level

b

Overhead Applied to Production: The overhead applied to production is found by multiplying the predetermined overhead rate by the actual direct labor hours used

c

Over(under)application Calculation: The over(under)application of manufacturing overhead is the difference between the actual manufacturing overhead cost and the overhead applied to production

d

Mathematical Calculation: Using the formula for over(under)application: Over(under)application = Actual Manufacturing Overhead - Overhead Applied to Production

e

Calculation Steps: - Predetermined overhead rate = Estimated total manufacturing overhead / Estimated activity level =

\frac{\$788,000}{20,000 \text{ hours}} = \$39.40 \text{ per direct labor hour}

- Overhead applied to production = Predetermined overhead rate * Actual direct labor hours =

\$39.40 * 20,000 \text{ hours} = \$788,000

- Over(under)application = Actual Manufacturing Overhead - Overhead Applied to Production =

\$761,000 - \$788,000 = -\$27,000

Thus, there is an underapplication of manufacturing overhead by $27,000

Key Concept

Over(under)application of manufacturing overhead

Explanation

The over(under)application of manufacturing overhead is determined by comparing the actual overhead costs incurred to the overhead costs applied to production based on the predetermined overhead rate. A negative result indicates underapplication, while a positive result indicates overapplication.

it's positive

That's correct! The overapplication of manufacturing overhead in this case is $27,000.00. Good job on getting the answer right! If you have any more questions or need further clarification, feel free to ask.

Stereo Corp. continued production of their popular radio line into 2018. The following information on inventory and production pertains to the year 2018. \begin{tabular}{|l|c|} \hline Cost of Goods Manufactured &

\$ 263,000

\\ \hline Beginning Finished Inventory &

\$ 0

\\ \hline Ending Finished Goods Inventory &

\$ 37,000

\\ \hline Overapplied Overhead &

\$ 7,000

\\ \hline \end{tabular} Calculate the adjusted Cost of Goods Sold for the year 2018.

A

Key Concept

Adjusted Cost of Goods Sold (COGS)

Explanation

To calculate the adjusted COGS, we start with the Cost of Goods Manufactured, add the Beginning Finished Inventory, subtract the Ending Finished Goods Inventory, and adjust for any overapplied or underapplied overhead. Since the overhead is overapplied, it means that the actual overhead costs were less than what was allocated, so we subtract the overapplied amount from the COGS. The formula is:

\text{Adjusted COGS} = \text{Cost of Goods Manufactured} + \text{Beginning Finished Inventory} - \text{Ending Finished Goods Inventory} - \text{Overapplied Overhead}

Given the numbers:

\text{Adjusted COGS} = \$263,000 + \$0 - \$37,000 - \$7,000 = \$219,000

\operatorname{Max}_{x, y} x+y

s.t.

p_{x} x+p_{y} y \leq m

Answer

The maximum value of

x + y

given the constraint

p_x x + p_y y \leq m

is

m

when

x = \frac{m}{p_x}

and

y = 0

, or

y = \frac{m}{p_y}

and

x = 0

.

Solution

a

Objective Function: The problem is to maximize

x + y

b

Budget Constraint: The constraint is

p_x x + p_y y \leq m

, where

p_x

and

p_y

are the prices of goods

x

and

y

respectively, and

m

is the total money available

c

Corner Solutions: Since we want to maximize

x + y

, and there are no other constraints on

x

and

y

besides the budget constraint, the maximum will occur at a corner solution where all money is spent on either

x

or

y

d

Calculation of Maximum

x + y

: If all money is spent on

x

, then

x = \frac{m}{p_x}

and

y = 0

, giving

x + y = \frac{m}{p_x}

. If all money is spent on

y

, then

y = \frac{m}{p_y}

and

x = 0

, giving

x + y = \frac{m}{p_y}

. Since we are maximizing

x + y

, we choose the larger of the two values

Key Concept

Linear Programming and Corner Solutions

Explanation

In a linear programming problem with a linear objective function and a single linear constraint, the maximum or minimum value of the objective function will occur at a corner solution, where one of the variables is at its maximum value given the constraint.

\begin{array}{r} \\ \max _{x, y} 6 x^{\frac{1}{4}} y^{\frac{3}{4}} \\ \text { s.t } \quad p_{x} x+p_{y} y \leq m \\ x \geq 0, y \geq 0\end{array}

like monotonicity and convexcity

Answer

Monotonicity and convexity are important properties in mathematical optimization that help determine the nature of the objective function and the feasibility of finding global optima.

Solution

a

Monotonicity: A function is monotonic if it is either entirely non-increasing or non-decreasing

b

Convexity: A function is convex if, for any two points on the graph of the function, the line segment connecting them lies above or on the graph. The mathematical condition for a function

f(x)

to be convex is

f(\lambda x_1 + (1-\lambda) x_2) \leq \lambda f(x_1) + (1-\lambda) f(x_2)

for all

x_1, x_2

in the domain of

f

and

\lambda \in [0,1]

Key Concept

Monotonicity and Convexity in Optimization

Explanation

Monotonicity helps in understanding the direction of change in the function's value, while convexity ensures that local minima are also global minima, which is crucial for optimization problems.

\begin{array}{r} \\ \max _{x, y} 6 x^{\frac{1}{4}} y^{\frac{3}{4}} \\ \text { s.t } \quad p_{x} x+p_{y} y \leq m \\ x \geq 0, y \geq 0\end{array}

check monotonicity and convexcity condition

Answer

To check for monotonicity and convexity, one must examine the first and second derivatives of the function in question.

Solution

a

Monotonicity: A function is monotonic if it is either entirely non-increasing or non-decreasing

b

Checking Monotonicity: To check for monotonicity, take the first derivative of the function and analyze its sign. If the first derivative is positive (or zero) across its domain, the function is non-decreasing. If it is negative (or zero), the function is non-increasing

c

Convexity: A function is convex if the line segment between any two points on the graph of the function lies above or on the graph

d

Checking Convexity: To check for convexity, take the second derivative of the function. If the second derivative is positive (or zero) across its domain, the function is convex

Key Concept

Monotonicity and Convexity in functions

Explanation

Monotonicity is determined by the sign of the first derivative, while convexity is determined by the sign of the second derivative.

\begin{array}{r} \\ \max _{x, y} 6 x^{\frac{1}{4}} y^{\frac{3}{4}} \\ \text { s.t } \quad p_{x} x+p_{y} y \leq m \\ x \geq 0, y \geq 0\end{array}

Answer

To solve the optimization problem, we need to apply the method of Lagrange multipliers.

Solution

a

Objective Function: The function to be maximized is the Cobb-Douglas production function

6x^{\frac{1}{4}}y^{\frac{3}{4}}

b

Constraints: The constraints are the budget constraint

p_x x + p_y y \leq m

and the non-negativity constraints

x \geq 0, y \geq 0

c

Lagrange Multiplier: Introduce a Lagrange multiplier

\lambda

for the budget constraint and form the Lagrangian

L(x, y, \lambda) = 6x^{\frac{1}{4}}y^{\frac{3}{4}} + \lambda(m - p_x x - p_y y)

d

First-Order Conditions: Take the partial derivatives of

L

with respect to

x

,

y

, and

\lambda

, and set them equal to zero to find the critical points

e

Solve the System: Solve the system of equations obtained from the first-order conditions to find the values of

x

,

y

, and

\lambda

that maximize the objective function subject to the constraints

Key Concept

Lagrange multipliers are used to find the maximum or minimum of a function subject to equality constraints.

Explanation

By setting up the Lagrangian with the given constraints and solving the system of first-order conditions, we can find the values of

x

and

y

that maximize the production function within the budget constraint.
