Question

Bob got a raise and he's hourly wage increased from $10 to $18 what is the percent increase?

Answer 1

In order to find the percent increase, let's first find the absolute increase, by subtracting the new value and the old value:

$18-10=8$

Now we just need to divide the absolute increase by the old value, then we will find the percent increase:

$\frac{8}{10}=0.8=80\text{\%}$

So the percent increase is 80%.
