Answer:
$11.23
Explanation:
Calculation for the selling price that would maintain the same contribution margin ratio as last year
Selling price per unit = $8.40
Variable cost per unit = $2.25
First step is to the Contribution margin per unit using this formula
Contribution margin per unit = Selling price per unit-Variable cost per unit
Contribution margin per unit= $8.40-$2.25
Contribution margin per unit = $6.15
Second step is to find the Contribution margin ratio using this formula
Contribution margin ratio= Contribution margin / Selling price per unit
Contribution margin ratio= $6.15/$8.40
Contribution margin ratio= 0.73*100
Contribution margin ratio=73%
Third step is to calculate for the Increase in variable cost per unit For coming year
Variable cost per unit will increase by 1/3
Increase in variable cost per unit = 6.15 x 1/3
Increase in variable cost per unit= $2.05
Variable cost per unit = 6.15+2.05
Variable cost per unit = $8.2
Last step is to find the selling price per unit using this formula
Selling price per unit =Variable cost per unit /Contribution margin ratio
Let plug in the formula
Selling price per unit = $8.2/0.73
Selling price per unit= $11.23
Therefore the selling price that would maintain the same contribution margin ratio as last year is $11.23
