Doug is going to the store to stock up on food for his dog. while in the store, doug decides to buy a single bag of dog treats as well. if a large bag of dog food costs $57 and a bag of dog treats costs $9, how many large bags of dog food, x, did doug buy if he spent $180 and all prices already include sales tax?

WELL if he only bought a single bag of treats we just need to subtract $9 from his total amount spent, then we can just worry about how many bags of dog food he bought.

180 - 9 = 171

If each bag of dog food costs $57 then we just divide it with the remaining total.

171 / 57 = 3

WHICH MEEEAANNNS:

Doug bought 3 bags of dog food. c:
