The city bike rental program is analyzing their growth in member rates. The number of regular members is growing by 4.7% per month. The number of VIP members is growing by 65% per year. Write a function to represent the number of regular members after t years. Then, write an equivalent function that represents the regular members with only 1 compounding per year. What is the effective yearly rate of growth of regular members

a) F(t) = N(1.047)^12t

b) F(t) = N(1 + 0.7352425166 )^t

c) 73.5%

Step-by-step explanation:

The growing is exponential in nature.

For the number of regular members growing at 4.7% per month

R = 4.7%

t = t × 12

N = initial number of members

A function to represent the number of regular members after t years will be

F(t) = N( 1 + 4.7%)^t×12

F(t) = N(1.047)^12t

An equivalent function that represents the regular members with only 1 compounding per year.

That is, t = 1

F(t) = N(1.047)^12(1)

Then, write an equivalent function that represents the regular members with only 1 compounding per year

(1 + 0.047)^12 = 1.7352425166 

F(t) = N(1 + 0.7352425166 )^t

What is the effective YEARLY rate of the growth for regular members? 

(1.7352425166 - 1) * 100

yearly rate ≈ 73.5%

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is symmetric about the line y = 120,000.
