Question

A price increases from $82 to $89.38. What is the percent of change

Answer 1

the cost goes up $7.38 which is 9% of $82

Answer 2

We first must find the difference between the two prices. So let's subtract:

`$89.38-82=7.38`

Now we take this difference and divide it by the original amount that the price was:

`(7.38)/(82) =0.09`

This is the decimal form of the answer. In order to make it a percent, we must multiply it by 100:

`0.09*100=9`

So the percent change in this price is 9%.
