Answer:
Mark−up percentage = 18.75%
Explanation:
Total manufacturing cost= Direct material + Direct labor + Variable overhead + Fixed overhead
= $36 + $24 + $18 + $40
= $118
Hence, the total manufacturing cost is $118.
Total selling cost = Fixed selling cost + Variable selling cost
Total selling cost = $28 + $14
Total selling cost = $42
Hence, the total selling cost is $42
Total cost = Total Manufacturing cost + Total selling cost
Total cost = $118 + $42
Total cost = $160
Mark−up percentage = ROI / Total cost * 100
Mark−up percentage = $30 / $160 * 100
Mark−up percentage = 0.1875 * 100
Mark−up percentage = 18.75%
