Answer:
Option (D) is correct.
Explanation:
Large drink:
Contribution margin per unit = Selling price - Variable cost
= $3.00 - $0.80
= $2.20
Small drink:
Contribution margin per unit = Selling price - Variable cost
= $1.00 - $0.50
= $0.50
Sales mix ratio 2:1
(2/3 × 100 = 66.67% for large drink
and 1/3 × 100 = 33.33% for small drink
Weighted contribution margin:
= Contribution margin per unit × sales mix percentage
= ($2.20 × 66.67%) + ($0.50 × 33.33%)
= $1.47 + 0.17
= $1.63 or $1.64 (approx)
