Question

Membership in a science club is expected to grow by about 6% per month. Currently there are 140 members in the club. In about how many months will membership reach 300 members?

Answer 1

Problem: How many months will membership reach 300 members?
Given: 140 members (current month)
            6% monthly increase of members 
            300 targeted members
Method: Multiplication and Division
Solution: To get the number of increased members per month
                 140 x .06  = 8.4 changed to 9 (because the numbers are persons)
               
               To get the number of months divide 300(target members) with the
               number of increased members per month.
        
                300 / 9 = 33.333 months Make 33 as 34 because of the points since                 we are looking for the number of months to reach 300 members.

Answer:  34 months
