You deposit $1000 in an account with an annual interest rate of r (in decimal form) compounded monthly. At the end of 5 years, the balance A is 60 A = 1000 1 + 12 1000(1+) Find the rates of change of A with respect to r when r = 0.08, r = 0.11, and r = 0.14. (Round your answer to two decimal places.) (a) r = 0.08 $ per 100 percentage points (b) r = 0.11 $ 0566.05 per 100 percentage points (c) r = 0.14 $ per 100 percentage points
