An initial investment amount P, an annual interest rate r, and a time t are given. Find the future value of the investment when interest is compounded (a) annually, (b) monthly, (0) daily, and (d) continuously. Then find (e) the doubling time Tfor the given interest rate. P = $27,000, r= 4.1%, t= 18 months a) The future value of the investment when interest is compounded annually is (Type an integer or a decimal. Round to the nearest cent as needed.) b) The future value of the investment when interest is compounded monthly is (Type an integer or a decimal. Round to the nearest cent as needed.) c) The future value of the investment when interest is compounded daily is $ (Type an integer or a decimal. Round to the nearest cent as needed.) d) The future value of the investment when interest is compounded continuously is $ (Type an integer or a decimal. Round to the nearest cent as needed.) 9) Find the doubling time for the given interest rate. T=Dyr (Type an integer or decimal rounded to two decimal places as needed.)
