What was the annual compound rate of growth in the price of the two fruits? (Do not round intermediate calculations. Round your answers to 2 decimal places.) Annual Compound rate growth for apples % Compound rate growth for oranges % ________________________________________ b. If the same rates of growth persist in the future, what will be the price of apples in 2030? (Do not round intermediate calculations. Round your answer to 2 decimal places.) Price of apples in 2030 $ c. What about the price of oranges? (Do not round intermediate calculations. Round your answer to 2 decimal places.) Price of oranges in 2030 $Explanation / Answer
Apples Price in 2000 = 0.98$ price in 2010 = 1.38$ 1.38 = 0.98(1+r)^10 (1+r)^10 = 1.408 taking log both sides 10*log(1+r) = log(1.408) log(1+r) = 0.1486 1+r = 1.0149 r = 1.49% Oranges price in 2000 = 0.76$ price in 2010 = 1.22 1.22 = 0.76(1+r)^10 solving like above we get r = 2.076% Now in 2030 price of apple = 1.32(1.0149)^20 = 1.77$ price of oranges = 1.22(1.02076)^20 = 1.84$
