Answer:
See below.
Explanation:
The formula to calculate target profit is as follows,
Target sales = Fixed costs + Target profit / contribution per unit.
Contribution = 120 - 80 = $40
For 10,000 in profits,
Target units = (50000+10000)/40
Target units = 1500 units
For 15000 in profits,
Target units = (50000+15000)/40
Target units = 1625 units
Hope that helps.
