3B. The following equation describes the conversion of a cash flow into an equivalent
equal payment series with N=10:
A= [800+20(A/G,6%,7)] * (P/A, 6%, 7) (A/P,6%,7) + [300(F/A, 6%, 3)-500] * (A/F,
6%, 10)
Reconstruct the original cash flow diagram.
How long will it take money to quadruple itself if invested at 13% compounded annually?
If the interest rate is 6% compounded quarterly, how long (number of quarters) will it take to earn $100 interest on an initial deposit of $300?
