Quizplus · Accepted Answer

The cost of a window is found by subtracting the markup from the selling price, so $106.81 - $34.69 = $72.12. The markup as a percent of cost is calculated by dividing the markup by the cost and then multiplying by 100, so ($34.69 / $72.12) * 100 = 48.1%. The markup as a percent of selling price is found by dividing the markup by the selling price and then multiplying by 100, so ($34.69 / $106.81) * 100 = 32.5%.
