Jeff bought x number of games for $32 each. He paid with a $100 bill. Which expression represents the amount of money Jeff received back from the cashier?

• 32 + x - 100

• 100 - 32x

• 32x - 100

• 100x + 32

Answer explanation

"Each" is a clue to multiply. Each game costs $32 but we don't know how many games were bought. x = number of games bought

To find how much was spent on games, we multiply 32 by x

Jeff had $100 to begin with, so we subtract the money spent on games from the $100 he started with.

100 - 32x
