Given:
Number of gym members in last quarter = 490
Number of gym members in this quarter = 686
To find:
The percent of increase in the number of members.
Solution:
We have,
Number of gym members in last quarter = 490
Number of gym members in this quarter = 686
Now, the percent of increase in the number of members.
![\%\text{ of increase}=\frac{{Members in this month - Members in last month}}{\text{Members in last month}}* 100](https://img.qammunity.org/2022/formulas/mathematics/high-school/1kdqzwz2st0uc2ve1dy5gf7ul73ph3gkne.png)
![\%\text{ of increase}=(686-490)/(490)* 100](https://img.qammunity.org/2022/formulas/mathematics/high-school/pzarly3fvlwr3rgllggrq8c01l0tdhtr7g.png)
![\%\text{ of increase}=(196)/(490)* 100](https://img.qammunity.org/2022/formulas/mathematics/high-school/9ka3cjnut4n3w6zdvbcujpyk818g5to09d.png)
![\%\text{ of increase}=(2)/(5)* 100](https://img.qammunity.org/2022/formulas/mathematics/high-school/gdkacz12f6346ilvv610l0k43byzvz76t6.png)
![\%\text{ of increase}=2* 20](https://img.qammunity.org/2022/formulas/mathematics/high-school/zj1fi1ajimvx25ktzcrclx2tjp5sktnybq.png)
![\%\text{ of increase}=40](https://img.qammunity.org/2022/formulas/mathematics/high-school/umcs1im1kban5q1zijpp4bwngbh4mlf102.png)
Therefore, the gym members increased by 40%.
