Answer:
464.35 units
Explanation:
The computation of units will need to be sold to break-even is shown below:-
Variable cost per unit = 25% × $225
= $56.25 per unit
Revised selling price = $225 + 40% increase
= $225 + $225 x 40%
= $315 per unit
Contribution per unit = Selling price per unit - Variable cost per unit
= $315 - $56.25
= $258.75
Current fixed costs = $133,500
Revised fixed cost = $133,500 - 10% × $133,500
= $120,150
Number of units required to break even = Revised fixed cost ÷ Contribution per unit
= $120,150 ÷ $258.75
= 464.35 units
