Question

Twila decides to purchase several party trays for her holiday party. She sees that a local store has relish trays for $18.95, cheese and cracker trays for $23.99, and cookie trays for $25.49. The store also has a coupon in its flyer for $5 off any purchase of $50 or more on party trays. Twila orders 1 relish, 1 cheese and cracker, and 2 cookie trays. At this store, discount coupons are applied after tax is calculated, so a sales tax of 8% was added to Twila’s purchase, and then coupon amount was deducted. If Twila was charged $96.43, determine if she paid the correct amount.


a.
Twila paid the correct amount for her purchase.
b.
Twila paid $4.00 too little for her purchase.
c.
Twila paid $0.40 too much for her purchase.
d.
Twila paid $2.51 too much for her purchase.

Answer 1

A

Subtotal = 18.95 + 23.99 + 2(25.49) = 93.92
Tax = 8% of 93.92 = 0.08·93.92 = 7.5136 → $7.51 (rounded)
Total after tax = 93.92 + 7.51 = 101.43
After $5 coupon = 101.43 − 5.00 = 96.43

Twila was charged $96.43, which is correct.
