If Emma had a 15 dollar gift card, and want wanted to buy an app that costs 3.99 and 7.99, how much money would she have left over?(plus tax too so think a few cents over)
So if you have 3.99+7.99 =11.98 with out tax. You add 8 cents extra For tax you would get 4.79 and 8.79, you add that and it equals 13.58 with tax include
