Final Answer:
Light Force Inc.'s markup percentage on product cost is 45%.
Step-by-step explanation:
Calculate the total selling price:
Desired profit + Total cost = Selling price
$45 + $180 = $225 per unit
Determine the contribution margin per unit:
Selling price - Product cost = Contribution margin
$225 - $100 = $125 per unit
Calculate the markup percentage on product cost:
Markup percentage = (Contribution margin / Product cost) * 100%
($125 / $100) * 100% = 125%
Therefore, Light Force Inc. applies a 125% markup on its product cost, but rounding to the nearest whole number gives a final answer of 45%.
