Answer:
18.24%
Step-by-step explanation:
Annual rate of return is used in determining the return on an investment over a 12 month or one year period.
Annual rate of return = [(future value / cost ) ^( 1/n) ] - 1
future value = 2150
present cost = 1100
n = number of years = 4
(2150 / 1100)^(1/4) - 1 = 0.1824 = 18.24%
