Answer:
45%
Explanation:
Given the following :
Sales unit = 64000
Sales revenue = $1,280,000
Direct materials and directly labor = $640,000
Other variable cost = $64,000
Fixed cost = $360,000
Contribution margin ratio:
(Sales revenue - variable expenses) / sales revenue
Total variable expenses = (Direct materials and directly labor + other variable expenses)
Total variable expenses = (640000 + 64000) = $704,000
Contribution margin ratio :
$(1,280,000 - 704,000) / $1,280,000
$576,000 / $1,280,000
= 0.45
0.45 * 100 = 45%
