Mrs. jones needs to buy some purrfect brand cat food. if each can costs $0.78 and has coupons for $2 off the entire purchase, how many cans of cat food can she buy for under $7?
well, she can basically spend $9 worth of money since shes getting $2 off. so, if we multiply $0.78 by 11 we get $8.58, which is under $7 when we subtract the $2 off coupon. meaning she can buy 11 cans for under $7
