Answer:
d) 127,000 members
Step-by-step explanation:
A = Accrued Amount (principal + interest)
P = Principal Amount of members = 23,000 initial members
r = Annual Nominal Interest Rate as a decimal = .05
t = years left to increase (2020-1985 = ) 35 years
n = number of times amount compounds per time = 1 time/year
23,000 initial members( 1 + .05/1)^1*35
23,000*(1.05)^35 = 23,000*(5.516) = 126, 868 = around 127,000 members
