a) $38,650; 48.31% b) $74,850; 93.56%

c) $60,650; 75.81% d) $32,950; 41.19%

A) $38,650; 48.31%

Explanation:

The computation of the contribution margin and the contribution margin ratio is shown below:

Contribution margin = Service Revenue - Cleaning Supplies Used - wages expense

= $80,000 - $22,000 - $19,350

= $38,650

The variable cost is Cleaning Supplies Used + wages expense

And, the contribution margin ratio equals to

= (Contribution margin ÷ sales) × 100

= ($38,650 ÷ $80,000)  × 100

= 48.31%
