Hideki buys 2 sweaters for $18 each. He can use one of the following coupons:
Coupon 1: Buy one, get one 40% off
Coupon 2: 25% off entire purchase
Which coupon should Hideki use to get a better deal?
To determine which coupon will provide a better deal for Hideki, let's calculate the total cost of the sweaters with each coupon.
Coupon 1: Buy one, get one 40% off. Since Hideki is buying 2 sweaters, he will get a 40% discount on one of them. The cost of the first sweater remains $18, and the second sweater will be reduced by 40%, which is 0.4 * $18 = $7.20 discount. Thus, the second sweater will cost $18 - $7.20 = $<<18-7.2=10.80>>10.80.
The total cost of the two sweaters is $18 + $10.80 = $<<18+10.80=28.80>>28.80.
Coupon 2: 25% off entire purchase. With this coupon, Hideki will receive a 25% discount on the total cost of his purchase. The total cost of the two sweaters is $18 + $18 = $<<18+18=36>>36.
The discount he will receive is 0.25 * $36 = $<<0.25*36=9>>9.
Thus, the total cost of the two sweaters with this coupon is $36 - $9 = $<<36-9=27>>27.
Comparing the two totals, Hideki will get a better deal by using Coupon 2, which will give him a total cost of $27 for the two sweaters.
