计算一下里面的步骤是否正确
Solution by Steps
step 1
Calculate the new survival rate for cod: 20%×2,000,000=0.20×2,000,000=400,00020\% \times 2,000,000 = 0.20 \times 2,000,000 = 400,000
step 2
Calculate the revenue for cod: 400,000×$5=$2,000,000400,000 \times \$5 = \$2,000,000
step 3
Calculate the new feeding costs for cod: 21×40×$400=21×40×400=$336,00021 \times 40 \times \$400 = 21 \times 40 \times 400 = \$336,000
step 4
Calculate the increased weekly feeding cost for cod: 80×52=80×52=$4,16080 \times 52 = 80 \times 52 = \$4,160
step 5
Calculate the total feeding costs for cod: 336,000+4,160=336,000+4,160=$340,160336,000 + 4,160 = 336,000 + 4,160 = \$340,160
step 6
Calculate the total variable costs for cod: 340,160+24,000+15,600=340,160+24,000+15,600=$379,760340,160 + 24,000 + 15,600 = 340,160 + 24,000 + 15,600 = \$379,760
step 7
Calculate the operating income for cod: 2,000,000−379,760=2,000,000−379,760=$1,620,2402,000,000 - 379,760 = 2,000,000 - 379,760 = \$1,620,240
step 8
Calculate the new survival rate for salmon: 14%×2,000,000=0.14×2,000,000=280,00014\% \times 2,000,000 = 0.14 \times 2,000,000 = 280,000
step 9
Calculate the revenue for salmon: 280,000×$9=280,000×9=$2,520,000280,000 \times \$9 = 280,000 \times 9 = \$2,520,000
step 10
Calculate the new feeding costs for salmon: 35×50×$400=35×50×400=$700,00035 \times 50 \times \$400 = 35 \times 50 \times 400 = \$700,000
step 11
Calculate the increased weekly feeding cost for salmon: 80×52=80×52=$4,16080 \times 52 = 80 \times 52 = \$4,160
step 12
Calculate the total feeding costs for salmon: 700,000+4,160=700,000+4,160=$704,160700,000 + 4,160 = 700,000 + 4,160 = \$704,160
step 13
Calculate the reduced water treatment costs for salmon: 1×50×$600=1×50×600=$30,0001 \times 50 \times \$600 = 1 \times 50 \times 600 = \$30,000
step 14
Calculate the total variable costs for salmon: 704,160+30,000+15,600=704,160+30,000+15,600=$749,760704,160 + 30,000 + 15,600 = 704,160 + 30,000 + 15,600 = \$749,760
step 15
Calculate the operating income for salmon: 2,520,000−749,760=2,520,000−749,760=$1,770,2402,520,000 - 749,760 = 2,520,000 - 749,760 = \$1,770,240
Answer
The calculations for the new filtration system for both cod and salmon are correct.
