Question

Allie's pay is increased from $12.50 per hour to $13.25 per hour. What was the percent increase in her hourly pay?

Answer 1

Let's assume that Allie's pay before the increase is the 100% of the pay. Then, using a rule of three, we get the following:

`\begin{gathered} 12.50\rightarrow100\% \\ 13.25\rightarrow x\% \\ \Rightarrow x=(13.25\cdot100)/(12.50)=(1325)/(12.50)=106 \\ x=106\% \end{gathered}`

therefore, the percent increase in Allie's pay is 106 - 100 = 6%
