Final answer:
The percent of markup from the store cost of $125 to the selling price of $168.75 is calculated to be 35%.
Step-by-step explanation:
To find the percent of markup, you'll need to calculate the difference between the selling price and the store cost, and then find out what percentage this difference is of the store cost. The store cost is $125 and the selling price is $168.75. The markup is therefore $168.75 - $125 = $43.75. To determine what percentage $43.75 is of $125, you divide $43.75 by $125 and then multiply by 100. That gives you ($43.75 / $125) * 100 = 35%. Therefore, the percent of markup is 35%.
The markup is calculated by subtracting the store cost from the selling price, then dividing the result by the store cost and multiplying by 100. In this case, the markup is $168.75 - $125 = $43.75. The percent of markup is ($43.75/$125) * 100 = 35%. Therefore, the correct answer is D. 35%.
