Camille uses a 20% off coupon when buying a sweater that costs $47.99. If she also pays 6% sales tax on the purchase, how much does she pay?

47.99

well assuming that 20% off coupon only applies 47.99 which 47.99*.8=$38.39 then apply the 6%= 38.39*1.06=$40.70. 

assuming 20% on final then 47.99*1.06*.8=40.70 

as you can see it does not matter which way since its the same total
