Nathan bought a pair of boots for $79.95 and 2 shirts for $19.99 each. The sales tax is 7.5%. How much did Nathan pay for all the items, including tax?
First, add up his total. 79.95+2*19.99=119.93 Then multiply by 1.075 (this will add the tax to the amount) That gives us 128.92475, which we can simplify to 128.92 He had to pay $128.92
