Jeremy buys 2 sweaters for $18 each. he can use only one of the following coupons:

coupon 1: buy one, get one 40% off

coupon 2: 25% off the entire purchase

Jeremy should use coupon 2 because when you multiply both the sweaters (36) by .25 you get 9, and then you subtract 36 by 9 which is 27.

But when you use coupon 1 you multiply 18 by .40 which is 7.20 where you subtract 18 by 7.20 which is 10.80. You then add 10.80 with 18 which is 28.80.

I don't even know what the question is but I found the same problem and this was the answer

0 is its x and y coordinate
