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.
[tex]\%\text{ of increase}=\dfrac{{Members in this month - Members in last month}}{\text{Members in last month}}\times 100[/tex]
[tex]\%\text{ of increase}=\dfrac{686-490}{490}\times 100[/tex]
[tex]\%\text{ of increase}=\dfrac{196}{490}\times 100[/tex]
[tex]\%\text{ of increase}=\dfrac{2}{5}\times 100[/tex]
[tex]\%\text{ of increase}=2\times 20[/tex]
[tex]\%\text{ of increase}=40[/tex]
Therefore, the gym members increased by 40%.
