Basic Math

Suppose you bought an exercise machine for $161, books for $ 36, CD’s for $32 and a watch for $45. If the state sales tax is 4 percent, how much did you spend?First, you add up all the prices. 161+36+32+45= 274Then you multiply it by the percentage.274*.04=10.96Next you add that to the original total.274+10.96=284.96
