Question

Monica paid sales tax of $4 when she bought a new bike helmet. If the sales tax rate was 8%, how much did the store charge for the bike helmet before tax?

Answer 1

50 = price

Explanation:

The tax is equal to the original price times the tax rate

tax = price*rate

4 = price * 8%

4 = price * .08

Divide each side by .08

4 / .08 = price

50 = price
