Answer:
Step-by-step explanation:
The total return is the rate of increase over the whole period:
% change = (11100/6300 -1) × 100% = 76.2%
The annual return is the rate of return that gives this growth over 20 years:
(1 +r)^20 = 1 +76.2%
r = 1.762^(1/20) -1 ≈ 2.87%
The total return is about 76.2%; the annual return is about 2.87%.
