so, if we take 500 to be the 100%, what is the 5% off of it then?
[tex]\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
500&100\\
x&5
\end{array}\implies \cfrac{500}{x}=\cfrac{100}{5}\implies \cfrac{500\cdot 5}{100}
=x[/tex]
so in 1 year she makes "x" bucks, in 6 years she'll make then 6x.
