Step-by-step explanation: so if you buy 1 bag of dog food that is $35 and you only have $100 so subtract $35 from $100 and you have $65 left so then you have to buy 2 chew toys and those are 12 dollars so do 12+12 and you get 24 so subtract $24 from the $65 and you get 41 if she wants to buy it again 3 times she wouldn't have enough
