Question

Sam bought brushes for $8, a palette for $5, and oil paints for $15. He paid $29.82 in all. What sale-tax rate did Sam pay?

Answer 1

Add the cost of the three items:

8 + 5 + 15 = $28

Subtract that amount from the total:

29.82 - 28 = $1.82 ( amount he paid in tax)

Divide the tax amount by the cost of the items:

1.82 / 28 = 0.065

Multiply that by 100:

0.065 x 100 = 6.5% sales tax rate
