Determine the effective rate ofgrowth per year for regular members. Which type of member is growing at a faster rate?a What is the effective YEARLY rate of the growth for regular members?b. Which type of member is growing at a faster rate?

Accepted Solution

A:

Answer: a) 73.52% b) Regular membership is growing fasterStep-by-step explanation:a) r(t) = r0·1.047^(12t) . . . . regular members after t years, where r0 is the initial value of regular members at t=0.Equivalently, this is ... r(t) = r0·(1.047^12)^t ≈ r0·1.7352^tThis shows the effective annual growth rate for regular members is 73.52%.__b) The 74% yearly growth rate of regular members is higher than the 65% yearly growth rate of VIP members. Regular membership is growing faster.
