Question

A trampoline was originally priced at $72, but Brennan waited to buy it until the trampoline was on sale for 70% off. If he paid 5% sales tax on the sale price, how much did he pay in total?

Answer 1

$52.92

Explanation:

The sale price was 0.70($72), or $50.40.

Then the price paid, plus the tax, is 1.05($50.40), or $52.92.

You could, if you wished, do all these calculations on one line:

1.05(0.70)($72) = $52.92.
