Discount Calculation on Marked Price

A grocery store typically marks up the price of its organic produce by 25%. If an organic apple costs the store $2.40, what percentage discount must the store offer on the marked price in order to sell the apple at a price that is 10% lower than the original cost price?

To find the marked price, first calculate what it would be after the markup. Then determine what the selling price would be at a 10% discount from the original cost price. Finally, figure out what percentage discount off the marked price achieves that selling price.
