# If you earn $18 and receive a pay increase of 12% how much money will you make? ##### 1 Answer Apr 4, 2015 The answer is $18+$2.16=$20.16

Remember: 12%-=12/100

You should calculate 12% of $18$ and add it up to $18$ to find the new salary.

To calculate 12% of $18$:

If you earn $100 you would receive $12 pay increase. But you earn $18 so we don't know the increase (lets call it $k$) Since 12% is always 12%: $\frac{12}{100} = \frac{k}{18}$$k = 18 \cdot \left(\frac{12}{100}\right) = \frac{18 \cdot 12}{100} = \frac{216}{100} = 2.16$As you can see in this step, if you want to know $x$percent of something, you can just multiply something with $\frac{x}{100}$. The answer is $18+$2.16=$20.16
