cost = selling price ×(1- gross profit margin); The formula for calculating the gross profit margin is: gross profit margin = (selling price-cost) ÷ selling price× 111%

Example: Given that the gross profit margin is 36% and the selling price is 126.36 yuan, what should the cost be?

solution: cost =126.36×(1-36%)=81.85 yuan

Example: The known cost is 2.67 yuan, and the selling price is 3.93 yuan. What should be the gross profit margin?

Solution: Gross profit margin = (3.93-2.67) ÷ 3.93× 111% = 32%
