Based on the price change, the decrease in sales, and the variable cost, the breakeven sales level for Eastern Semiconductor would be 375 units.
The breakeven point can be found by the formula:
= [Change in fixed price - (Change in selling price x decrease in sales)] / [New selling price - Variable cost]
Change in selling price is:
= New selling price - Original selling price
= 200 - 220
= -$20
Solving gives:
= [ 0 - ( -20 x 3,000)] / [200 - 40)
= 375 units
