Question

Desk cost $349.50 once delivered invoice reflects $387.22. If tax is 7.5% how much was the shipping charge?

Answer 1

Shipping charge was $11.51

Explanation:

Subtracting this amount from the total paid, $387.22, we get $11.51 as the shipping charge.

Check: Does $349.50 + $11.51 + $24.47 = $387.22? Yes
