Answer:
increase in sales required = $10,417
Correct option is (c)
Explanation:
Let the increase in sales required be $Y
Sale of food operation = 60% of Y
= 0.6Y
Variable cost of food operation = 30%
Hence, contribution margin of food operation = 70%
Contribution margin of food operation = 0.6Y x 70%
= $0.42Y
Sale of bar operation = 40% of Y
= 0.4Y
Variable cost of bar operation = 25%
Hence, contribution margin of bar operation = 75%
Contribution margin of bar operation = 0.4Y x 75%
= $0.3Y
Total contribution margin of food and bar operation = 0.42Y + 0.3Y
= 0.72Y
Increase in operating income = $7,500
Hence, 0.72Y = 7,500
Y = 7,500/0.72
= $10,417
Hence, increase in sales required = $10,417
Correct option is (c)
