Compound annual growth rate of apples, g = (Price of apples in 2017/Price of apples two years earliler)^(1/2) - 1
g = (1.61/1.40)^(1/2) - 1
g = 0.07238052948
Compound annual growth rate of apples, g = 7.238052948% = 7.24%
Compound annual growth rate of organges, g = (Price of oranges in 2017/Price of oranges two years earliler)^(1/2) - 1
g = (1.25/1.11)^(1/2) - 1
g = 0.06119089995
Compound annual growth rate of oranges, g = 6.119089995% = 6.12%
Number of compounding years until 2030 = 2030 - 2017 = 13
FV = PV * (1 + g)^n
Price of apples in 2030 = 1.61 * (1 + 0.07238052948)^13
Price of apples in 2030 = 3.9935749391 ~ $3.99
Price of oranges in 2030 = 1.25 * (1 + 0.06119089995)^13
Price of oranges in 2030 = 2.7053641798 ~ $2.71
