Answer:
If the machine is purchased, the contribution margin per unit will be $39.00
Explanation:
Contribution margin per unit is the amount that each additional unit sold contributes towards a company’s fixed costs and profit and calculated by following formula:
Contribution Margin per Unit = Sales Price – Variable Cost per Unit
If the machine is purchased, variable costs will decrease by $5.00 per unit
Variable Cost per Unit = $36.00 - $5.00 = $31.00
Contribution Margin per Unit = $70.00 - $31.00 = $39.00
