Answer:
The hiking club's member count increased by 48%.
Step-by-step explanation:
We are given two data values: 25 members and 37 members. We need to determine how many members the club gained first. We can set up an equation where we solve for an unknown, or<em> x</em>, in this case.

The club increased by 12 members, so now we can divide this value by the initial amount of members and multiply the decimal we receive by 100 to express it in percentage form.

Therefore, the club's member count increased by 48%.
