Question

Membership in the Volunteers Club increased by 15% from last year. If the number of members last year was m, complete a simplified expression to represent the number of members this year.

Answer 1

I think there is a mistake in this problem

Answer 2

Answer: a simplified expression to represent the number of members this year is: x = 1.15 * (m)

Step-by-step explanation:

For this case what you can do is the following rule of three:

m ---> 100%

x ----> 115%

Clearing the value of x we have:

x = (115/100) * (m)

x = 1.15 * (m)
