Given:
The number of students in a school club increased from 40 to 44.
To find:
By what percent did the number of students in the club increase?
Solution:

Increased in number of students divided by In the past, number of students in a club multiplied by 100
![(4)/(40) *100=(400)/(40) =10\%](https://img.qammunity.org/2021/formulas/mathematics/high-school/j2nzxe5cmeb1ckmaj08p46aaby0n20h389.png)
