Answer:
33%
Step-by-step explanation:
Profit ÷ Required Investment = Desired rate of return on investment
Profit ÷ 500,000 = 0.13
Profit = $65,000
Gross Profit required:
= Profit + Selling and administrative expenses
= $65,000 + $222,100
= $287,100
Gross profit per unit required:
= Gross Profit required ÷ Number of units sold
= $287,100 ÷ 30,000
= $9.57
Thus, selling price:
= Gross profit per unit required + Unit product cost
= $9.57 + $29
= $38.57
Markup:
= selling price ÷ Unit product cost
= 38.57 ÷ 29
= 1.33
