Answer
For part (a), you must repay 10,329,000attheendofthe60−dayperiod.Forpart(b),youmustrepay10,662,842 at the end of the second 60-day period. Solution
a
Calculation of Repayment Amount for the First 60-Day Period:
The amount to be repaid can be calculated using the formula for the future value of a present amount at simple interest: $FV = PV(1 + rt)$, where $PV$ is the present value, $r$ is the rate, and $t$ is the time in years. Given that $PV = $10,000,000, $r = 6.58\% = 0.0658$, and $t = \frac{60}{365}$ years, we can calculate the future value as follows: $FV = $10,000,000 \times (1 + 0.0658 \times \frac{60}{365}) = $10,329,000.
b
Calculation of Repayment Amount for the Second 60-Day Period:
Assuming the rate has not changed, we use the future value from part (a) as the new present value and apply the same formula: $FV_{\text{new}} = FV_{\text{old}}(1 + rt)$. With $FV_{\text{old}} = $10,329,000, $r = 0.0658$, and $t = \frac{60}{365}$ years, the new future value is $FV_{\text{new}} = $10,329,000 \times (1 + 0.0658 \times \frac{60}{365}) = $10,662,842.
Key Concept
Simple Interest Calculation
Explanation
The repayment amount for commercial paper is calculated using the simple interest formula, which takes into account the principal amount, the interest rate, and the time period of the loan.
Key Concept
Rollover of Commercial Paper
Explanation
When commercial paper is rolled over, the future value of the initial borrowing becomes the present value for the next borrowing period, and the same interest calculation is applied again to determine the new repayment amount.
