To find a percent change, you can follow these steps:
1.-calculate the difference between the two numbers that you are comparing:
[tex]\text{Change = New Number - Original Number }[/tex]2.-Then, the increase must be divided by the original number and multiply the result by 100:
[tex]\text{ \% change = }\frac{\text{Change}}{\text{Original number}}\cdot100[/tex]3.- If the answer is negative, then it is a decrease, if it's positive, then it is an increase.
For example, lets find the percent change of 40 to 65:
[tex]\begin{gathered} \text{New Number: 65} \\ \text{Original Number: 4}0 \\ \Rightarrow Change=65-40=25 \end{gathered}[/tex]then:
[tex]\text{ \%change=}\frac{25}{40}\cdot100=62.5[/tex]since the percent change is positive, we have that there is an increase of 62.5%
