Answer
First, we can divide the increase by the original amount to get a decimal number. We then express this decimal number as a percent. To express a decimal number as a percent, we move the decimal point two places to the right and attach the percentage sign.
For example:
The amount increases from 10 to 18. We can see that the original amount increased by 8.
$\frac{increase}{original ~amount} = \frac{8}{10} = 0.8 = 80\%$
The percent increase is 80%
