That's your answer.
The item would cost approximately $45. You can do this by taking the price of the item ($60) and multiply by the percent (25%). 60 x 0.25 = 15. That is the discount you would subtract from the item itself. Now you would take the original price ($60) and subtract the discount ($15). 60 - 15 = 45.
