Final Answer:
Trap-Ease's markup percentage from its sales to retailers is 60.4%.
Step-by-step explanation:
Trap-Ease sells its product to retailers at 99 cents per unit, while the manufacturing cost amounts to 31 cents per unit, and a royalty fee of 8.2 cents applies. The total cost per unit is calculated by adding the manufacturing cost and royalty fee, totaling 39.2 cents. The difference between the selling price and the total cost is the markup, which is 59.8 cents per unit.
To find the markup percentage, this figure is divided by the selling price (59.8/99) and multiplied by 100, resulting in a markup percentage of 60.4%. This means that 60.4% of the selling price accounts for covering manufacturing costs, royalties, and profit margin for Trap-Ease's product when selling to retailers.
Correct answer: 60.4%.
