Answer:
D) It decreases about 16 units.
Step-by-step explanation:
Currently Keene's break even point in units = total fixed costs / contribution margin
total fixed costs = $5,600
contribution margin = selling price - contribution margin = $20 - $6 = $14
Keene's current break even point = $5,600 / $14 = 400 units
If Keene's variable costs decrease by 10%, the new contribution margin will be = $20 - $5.40 = $14.60
Keene's new break even point = $5,600 / $14.60 = 383.56 ≈ 384 units
this represents a 4% decrease (16 units less)
