If I bought shoes for 32.30 with 15% off 7%sales tax a 25dollar gift card but had a coupon that was forgotten for 5%off the original price what should have I paid
Accepted Solution
A:
Answer: $4.37 cash outlay $29.37 total amount paid, partly with gift cardStep-by-step explanation:The discount was ... 0.15 × $32.30 = $4.845 ≈ $4.85So the price to which tax is added is ... $32.30 -4.85 = $27.45The amount of tax is 7% of this value, or ... tax = $27.45 × 0.07 = $1.9215 ≈ $1.92So, payment is made on the amount ... $27.45 + 1.92 = $29.37$29.37 is the total amount paid.If $25 is paid using a gift card, then the cash outlay is $4.37._____Usually only a single coupon can be applied to a given purchase. Since the 15% store discount exceeds the amount of the 5% coupon left at home, it makes more sense to claim the 15% store discount and save the 5% coupon for another time.__Alternate interpretationIf, by some magic, both discounts could be applied, then the amount to be paid is $27.65, of which $2.65 exceeds the gift card amount. The calculation proceeds the same way, except that 20% is used instead of 15%.
