Answer:
A
Explanation:
The formula for calculating future value:
FV = P (1 + r)^n
FV = Future value
P = Present value
R = interest rate
N = number of years
Security A : 11 = 1( 1 + r)^15
11^(1/15) = 1( 1 + r)
1.173 = 1 + r
r = 1.173 - 1
r = 17.33%
Security A : 16 = 1( 1 + r)^15
16^(1/15) = 1( 1 + r)
1.20 = 1 + r
r = 1.2 - 1
r = 0.2
r = 20%
Security B earned a higher average annual rate of return as 20% is greater than 17.33%
