Question

Kenny owned so many baseball cards that he sold 82 of them. After selling the cards, he still had 159 left. Write and solve an equation to find the number of baseball cards b Kenny had originally.

Answer 1

Let b be the number of cards Kenny originally owned.

Since he sold 82 cards, this means that he has :

`b-82`

We know that he still has 159 cards left, that means that:

`b-82=159`

Now we solve it:

`\begin{gathered} b-82=159 \\ b=159+82 \\ b=241 \end{gathered}`

Therefore, he originally had 241 baseball cards.
