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.

Respuesta :

We have:

each CD = x

so

[tex]221+11x=256[/tex]

and solve for :

[tex]\begin{gathered} 221+11x-221=256-221 \\ 11x=35 \\ \frac{11x}{11}=\frac{35}{11} \\ x=3\frac{2}{11}=3.18 \end{gathered}[/tex]

answer: 3 CDs
