Shona is buying a rug for her room. store a has the rug for $45 with a 10% discount. store b has the same rug for $46 and is offering a $10 rebate. the sales tax is 6% on either purchase. if shona only has $40 to spend, which store will she purchase the rug from, and how much will she have left over?

Store A :
0.90(45) = 40.5040.50 + .06(40.50) = 40.50 + 2.43 = 42.93

store B :
46 - 10 = 3636 * .06(36) = 36 + 2.16 = 38.16

she would have to purchase the rug from store B...because she doesn't have enough money to purchase it from store A. She would have (40 - 38.16) = $ 1.84 in change.

I find this question to be a little misleadingbecause on a rebate, u dont get the discount right awayu first pay full price, and then later u get the discount mailed back to you. So actually, she wouldn't have enough money at either store.

What’s the improper fraction?
