Question

After she worked a year at $9 an hour. Alisha's boss gave her a 10% pay raise. What was Alisha's new hourly pay rate?

Answer 1

Let:

Po = Old pay rate = $9/h

Pn = New pay rate

r = Pay raise = 10% = 0.1

So, the new hourly pay rate is:

`\begin{gathered} Pn=Po+0.1Po \\ Pn=9+0.1\cdot9 \\ Pn=9.9 \end{gathered}`

Answer:

$9.9/h
