You have a $20 coupon that can be applied to the purchase of a graphing calculator. When you get to the store you find that they are offering 15% off calculators. But, you can’t use your coupon and get the 15% discount. This makes you wonder what the cost of a calculator would be for your coupon and the 15% off discount to be the same. Find the original price of a calculator where you would pay the same amount whether you used the coupon or got the discount.
