Question

You have a job earning $12.50 per hour, and you receive a raise so that you earn $13.25 per hour. What is the percent change in your salary

Answer 1

$increase = 13.25 - 12.50 \\ increase = 0.75 \: dollars$

$12.50 = 100\% \\ 0.75 = x\%$

$12.50x = 100(0.75) \\ x = \frac{100(0.75)}{12.50} = \frac{75}{12.5} = 6\%$
