Question

Jimmy has a certain amount of money. If he spends $12, then he has one-fifth of the original amount. How much money did Jimmy have originally?

Answer 1

Let x be the original amount of money Jimmy had. Since he spent 12 and has the fifth of x this we have:

`\begin{gathered} x-12=(x)/(5) \\ x-(x)/(5)=12 \\ (4)/(5)x=12 \\ x=(12)/((4)/(5)) \\ x=15 \end{gathered}`

Then, he had $15 originally.
