$57.78

10% of 60 is 6 so the price is 60-6 or 54. Now you must add the sales tax. 7% of 54 is $3.78 so add that to 54.

Simply follow the directions to create an equation. 60 is the original price, but you have a 10% off coupon so then it's (60*.90) sales tax needs to be included to the result. So the final equation is (60 * .90) * 1.07
