Question

Carlos spent 1/5 of his money he saved on a CD. The CD cost $12. How much money did Carlos save before buying the CD?

Answer 1

We have the next equation

x is the money that Carlos saved

`(x)/(5)=12`

we need to isolate the x

`\begin{gathered} x=12\cdot5 \\ x=60 \end{gathered}`

Carlos saved before buying the CD, $60.
