Final answer:
By subtracting the cost to store from the selling price and dividing the result by the original cost, we find a markup percentage of 75%.
Step-by-step explanation:
To find the % of markup, we need to calculate how much the selling price is above the cost to store. Then, we find the percentage that this increase represents of the original cost.
First, we find the difference between the selling price and the cost to store:
Selling price - Cost to store = $3237.50 - $1850 = $1387.50
Next, we calculate the markup percentage by dividing the increase by the original cost and then multiplying by 100 to
get the percentage:
(Increase / Cost to store) * 100 = ($1387.50 / $1850) * 100 = 75%
So the percentage of markup is 75%, which corresponds to option c).
