Question

John is at Staples buying a few items for math class. He buys a notebook for $1.49, a calculator for $12.49, and a pack of highlighters for $3.50. The sales tax is 7%. How much does John spend at the store including tax? Round to the nearest cent.

Answer 1

Answer: (1.49+12.49+3.50)+1.22 = $18.70

Explanation:

Add all the prices of stuff together

(1.49+12.49+3.50) = 17.48

Multiply by 0.07 to get the tax

(1.49+12.49+3.50)*0.07=1.22

Add the tax onto the previous answer

(1.49+12.49+3.50)+1.22
