Answer:
The contribution margin ratio is 35%
Step-by-step explanation:
The formula for contribution is given below:
Contribution margin = revenue − variable costs.
Contribution margin ratio is given as:
(Sales – variable expenses) ÷ Sales
In this case,contribution is given as 1000*($20-$13), in other words selling price per unit minus variable cost multiplied by number of units sold.
Contribution is $7000
contribution margin ratio =$7000/($20*1000)
=0.35 or 35%
The implies that Hollis Industries makes a contribution of 35% per unit of output sold,hence, the contribution contributes towards covering fixed costs and making profit overall
