Answer 1

25%

Explanation:

Given:

• Difference = 10
• Original = 40

Substitute the given values into the percent change formula:

`\begin{aligned}\sf Percent\:change & =\frac{\textsf{Difference between values}}{\textsf{Original value}} * 100\\\\& = (10)/(40) * 100\\\\& = (1)/(4) * 100\\\\& = (100)/(4)\\\\& = 25\%\end{aligned}`

Therefore, the percent change is 25%.
