Answer and Explanation:
a. The computation of revenue, costs, and profit per day for each alternative is shown below:-
Particulars A B C
Revenue 180 216 270
(120 × $1.50) (180 × $1.20) (180 × $1.50)
Costs
Lemonade 60 90 90
(120 × $0.50) (180 × $0.50) (180 × $0.50)
Rent $30 $30 $30
Advertising 0 0 0
Profit 90 96 150
For computing the profit we simply deduct the cost from the revenue
b. Since, C gave maximum profit. So, C is the right answer.
c. Since, Rent is not an accurate cost as rent is the same for all. so, it can be ignored. Hence, the correct answer is A.
d. Advertising is an equal cost as advertising differs across different alternatives, it should not be ignored.
Hence, the correct answer is A.
