sergij07 [2.7K]

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}=\dfrac{{Members in this month - Members in last month}}{\text{Members in last month}}\times 100

\%\text{ of increase}=\dfrac{686-490}{490}\times 100

\%\text{ of increase}=\dfrac{196}{490}\times 100

\%\text{ of increase}=\dfrac{2}{5}\times 100

\%\text{ of increase}=2\times 20

\%\text{ of increase}=40

Therefore, the gym members increased by 40%.
