Hmmmm. Well those Munchos do look good and we want to know how much they cost. We're getting pretty good at working with money, maybe we have enough to take a trip to the vending machine. But we need some more information. Here's what we wanted to know.

Over on the left is the amount of money she deposited into the vending machine. We figured out she put in a nickel and then three quarters. Down below is the money she got back in return. We know two dimes is 20 cents. Now we have to figure out the difference to know how much the vending machine kept for the Munchos.

Well, 80-20=60. There are many ways to solve it, but any way you go about it those Munchos cost 60 cents. Next up....how many different ways can you make 60 cents?
