Question

The sale price of a new compact disc player 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 purchases a player and some CDs for $256, how many CDs did he purchases.

Answer 1

We have:

each CD = x

so

`221+11x=256`

and solve for :

`\begin{gathered} 221+11x-221=256-221 \\ 11x=35 \\ (11x)/(11)=(35)/(11) \\ x=3(2)/(11)=3.18 \end{gathered}`

answer: 3 CDs
