Answer:
Contribution per unit is $30 while contribution margin ratio is 40%
Step-by-step explanation:
The contribution margin ration is derived with the below formula:
contribution margin ratio=margin/sales price
Margin=selling price-variable cost
Margin=$75-$45
Margin=$30
Contribution margin ratio=$30/$75
Contribution margin ration=40%
The contribution determines the to which the company can recover its fixed costs as well as make profits.
The contribution margin ratio shows margin as a percentage of sales price.A contribution margin ratio of 40% implies that variable cost is 60% of selling price,hence the balance of 40% is available to settle fixed costs and profit
