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

Answer:

$19.55

Step-by-step 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
