Question

Your dinner costs $21.50 before tax. If you used a fifteen percent off coupon

and then you are charged seven percent sales tax, what is your balance with tax?

Answer 1

$19.55

Explanation:

Discount = 15% of 21.50

= 0.15 * 21.50

= 3.225

= $ 3.23

Balance need pay = 21.50 - 3.23 = $ 18.27

Tax = 7% of 18.27

= 0.07 * 18.27

= $1.28

Balance with tax = 18.27 + 1.28 = $ 19.55
