You are purchasing 2 shirts at $15.00 (each) and 1 pair of jeans at $30.00 (each) you have a coupon for 10% off. How much is the total cost with the discount?
You subtract 10% off original price (100%) and get 90%. Bring the 1% value of $60 (0.6) you get from dividing the original cost by 100 and multiply that by the true cost 90 to find the answer.
