Answer:
Results are below.
Step-by-step explanation:
To calculate the break-even point in units and dollars, we need to use the following formulas:
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 400,000 / (100 - 45)
Break-even point in units= 7,273
Break-even point (dollars)= fixed costs/ contribution margin ratio
Break-even point (dollars)= 400,000 / 0.55
Break-even point (dollars)= $727,300
Contribution margin ratio= contribution margin / selling price per unit
Contribution margin ratio= 55 / 100= 0.55
