Complete Stop Driving School charges $500 per student to prepare and administer written and driving tests. Variable costs of $150 per student include trainers' wages, study materials, and gasoline. Annual fixed costs of $140,000 include the training facility and fleet of cars.

1.	For each of the following independent situations, calculate the contribution margin per unit and the breakeven point in units by first referring to the original data provided:
	a.	Breakeven point with no change in information.
	b.	Decrease sales price to $ 250$250 per student.
	c.	Decrease variable costs to $ 100$100 per student.
	d.	Decrease fixed costs to $ 122 comma 500$122,500.
2.	Compare the impact of changes in the sales price, variable costs, and fixed costs on the contribution margin per unit and the breakeven point in units.

Requirement 1. For each of the following independent situations, calculate the contribution margin per unit and the breakeven point in units:

Begin by showing the formula for contribution margin per unit and then enter the amounts to calculate the contribution margin per unit for each situation. (Abbreviation used: CM = contribution margin.)

Requirement 2. Compare the impact of changes in the sales price, variable costs, and fixed costs on the contribution margin per unit and the breakeven point in units.

First, compare the impact of changes in the sales price, variable costs, and fixed costs on the contribution margin per unit.

The contribution margin

decreases

does not change

increases

when the sales price decreases. The contribution margin

decreases

does not change

increases

when variable costs decrease. The contribution margin

decreases

does not change

increases

when the fixed costs decrease.

Now, compare the impact of changes in the sales price, variable costs, and fixed costs on the breakeven point in units.

The breakeven point

decreases

does not change

increases

when the sales price decreases. The breakeven point

decreases

does not change

increases

when the variable costs decrease. The breakeven point

decreases

does not change

increases

when fixed costs decrease.
