Answer 1

if the value of the stock investment decreased 20% over the last year, we can think that now we have the 80% of the initial value. So

To find the value of the stock investment a year ago, you can solve this equation:

`\begin{gathered} (100)/(80)\cdot13000\text{ = 16250} \\ \end{gathered}`

So the answer is 16250
