Explanation:
The first step will be know the Contribution Margin:

Variable Cost
Food 120
Other 8
Total 128
Next we do the Contribution Margin, which represent how much cash each guest generates to pay the fixed cost
500- 128 = 372
Then we Calculate the total fixed cost we need to pay
Rental 150,000
Advertising 50,000
Entertainment 4,000

A.Marginal Revenue $3
B. No
Explanation:
A.Calculation for the Marginal Revenue (MR) that the firm earn from sale of the output produced by the last worker employed
Based on the information given we were told that the Marginal Physical product of the last unit of labor was 5 units per hour in which the firm pays each worker an hourly wage of $15. Now let calculate the Marginal Revenue using this formula
Marginal Revenue = Employees hourly wages/Marginal Physical product unit of labor
Where,
Employees hourly wages=$15
Marginal Physical product unit of labor =5 units per hour
Let plug in the formula
Marginal Revenue =$15/5
Marginal Revenue =$3
B. No reason been that the current profit-maximizing hourly output was 100 units in which we were told that the firm sells at a price of $5 per unit. While the Marginal Revenue gotten in (A) above was $3 which is lesser or lower than $5 per unit which simply means that the firm does NOT sell its output in a well perfectly competitive market .
