Answer:
Results are below.
Step-by-step explanation:
First, we need to calculate the unitary variable cost:
Unitary variable cost= (1 - Contribution margin ratio)*selling price
Unitary variable cost= 0.70*54
Unitary variable cost= $37.8
Now, the break-even point in units and dollars:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 388,800 / (54 - 37.8)
Break-even point in units= 24,000
Break-even point (dollars)= fixed costs/ contribution margin ratio
Break-even point (dollars)= 388,800 / 0.3
Break-even point (dollars)= $1,296,000
If the desired profit is $226,800; the following formula is required:
Break-even point in units= (fixed costs + desired profit) / contribution margin per unit
Break-even point in units= (338,800 + 226,800) / 16.2
Break-even point in units= 34,914
Break-even point (dollars)= (fixed costs + desired profit) / contribution margin ratio
Break-even point (dollars)= 565,600 / 0.3
Break-even point (dollars)= $1,885,333
Finally, if the variable cost per unit decreases by $5.4:
Unitary variable cost= $32.4
Break-even point in units= 388,800 / (54 - 32.4)
Break-even point in units= 18,000
Contribution margin ratio= unitary CM / Selling price
Contribution margin ratio= 21.6/54= 0.4
Break-even point (dollars)= fixed costs/ contribution margin ratio
Break-even point (dollars)= 388,800 / 0.4
Break-even point (dollars)= 972,000
Break-even point (dollars)= (fixed costs + desired profit) / contribution margin ratio
Break-even point (dollars)= (388,800 + 226,800) / 0.4
Break-even point (dollars)= $1,539,000
