Question

The sale of a new compact disc is $221 at a local discount store. At the store where this sale is going on, each new CD is in sale for $11 each. If Kyle purchased a player and some CDs for $265, how many CDs did he purchase?

Answer 1

4 CDs

Explanation:

According to the statement we can propose the following equation

`\begin{gathered} 221+11x=265 \\ \text{ where x is the number of CDs} \end{gathered}`

Solving for x:

`\begin{gathered} 11x=265-221 \\ x=(44)/(11) \\ x=4 \end{gathered}`

Which meanshe he buy 4 CDs
