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? (1) 5 months. (2) 8 months. (3) 13 months. (4) 15 months

Answer 1

8 Months. you multiply 140*.06 which gets you 8.4. next you round your answer to 8. the .06 is equal to 6%. Hope This help! :)

Answer 2

A=p (1+r)^t
300=140 (1+0.06)^t
Solve for t
T=log(300÷140)÷log(1.06)
t=13 months
