Question

Sam had $50 before spending x dollars on new CDs. How much money does he have left?

x+50

50-x

50/x

50x

Answer 1

50 - x

• This is because you are looking for the amount of money he spent to find how much he has left.
• In order to do this, you need to subtract x, the amount he spent, from the total, 50, in order to get how much money he has left.

Hope this helps!
