    (Compound interest) To what amount will the following investments accumulate?
    a. $5,000 invested for 10 years at 10 percent compounded annually
    b. $8,000 invested for 7 years at 8 percent compounded annually
    c. $775 invested for 12 years at 12 percent compounded annually
    d. $21,000 invested for 5 years at 5 percent compounded annually

    We will use following formulae:
    F=P*((1+r)^n
    F=Future value, P= Principal r= rate of interest n=duration

    a. $5,000 invested for 10 years at 10 percent compounded annually

    Here P=5000, r=10%, n=10
    ...
