Answer:
$7.18
Explanation:
16.50 x 0.6 = 9.9 (multiplying by percent to find the total amount off)
16.50 - 9.9 = 6.6 (subtracting the amount of money you would get off from the original price)
6.6 x 0.0875 = 0.58 (rounded) (multiplied by the tax percentage to find how much tax would cost)
6.60 + 0.58 = 7.18 (add the sale price and sales tax)
$7.18 (final answer)
