Answer:
a. First, we need to calculate the total fixed costs:
Depreciation: $76,000 * 0.2 = $15,200
Interest: $35,000 * 0.08 = $2,800
Known costs: $3,000 + $2,500 + $8,400 + $3,600 + $9,800 + $41,600 = $72,900
Then, we need to calculate the required net income after tax:
Net income required: $80,000 * 0.22 = $17,600
Income tax rate: 28%
Required net income after tax: $17,600 / (1 - 0.28) = $23,571
Finally, we can calculate the required sales revenue by adding the fixed costs and the required net income after tax:
Required sales revenue: $72,900 + $23,571 = $96,471
b. To calculate the required average check, we need to divide the required sales revenue by the number of seats and the average seat turnover:
Required average check: $96,471 / 60 seats / 2.5 seat turns per day = $112.69
Therefore, the restaurant would need to achieve sales revenue of $96,471 next year in order to acquire the desired net income after tax. The required average check would be $112.69 if the restaurant is open 365 days, has 60 seats, and has an average seat turnover of 2.5 times per day.
Hope this helps!! :))
