Answer:
a) $12 per unit
b) $2,693 units
Explanation:
contribution margin ratio formula = contribution margin / total revenue
contribution margin = total revenue - variable costs
0.35 = (revenue - 7.80) / revenue
0.35revenue = revenue - 7.80
7.80 = 0.65revenue
revenue = 7.80/.65
revenue = 12
number of units required to increase revenue by $6,000:
= (fixed costs + desired profits) / contribution margin
= ($15,000 + $6,000) / $7.80 = $21,000 / $7.80 = 2,692.31 ≈ we must round up to $2,693 units
