Answer:
A) Lily, must sell a total of 800 plants to break even.
B) If Lily sells 480 units of both A and B she will have a net profit.
D) If Lily’s sales mix changes, her break-even point will stay the same.
Explanation:
break even point = total fixed costs / contribution margin
break even point in units = $24,000 / $30 = 800 units
current sales mix:
plants A = 800 units x 60% = 480 units
plants B = 800 units x 40% = 320 units
