To get the expression that shows the number of cards Wally has left, we need to subtract the number of cards he gave to his friend from the number of cards he collects each week.
Let's break down the information given:
- Wally collects 15 baseball cards each week.
- He gave 10 cards to his friend James.
To express the number of cards Wally has left, we subtract the cards given away from the cards collected each week. Here's the expression:
Total cards collected - Cards given away = Cards Wally has left
Putting the information into the expression, we have:
15 - 10 = Wally's remaining number of cards
Simplifying the expression:
5 = Wally's remaining number of cards
Therefore, the expression to show the number of cards Wally has left is "5".
