A potential project requires an initial investment of $75,000 at the beginning of the 1st year, and will give a net cash inflow of $25,000 per year (realized at the end of the 1st, 2nd and 3rd year respectively) for three years. The required rate of return is 15%. What is the Net Present Value? NPV = Ao + Sum from t=0 to t=n of Ft /(1+R)t

169. What is the future value at the end of year 13 of an investment that starts at $6,000 and grows by 7% per year for 13 years ($6,000 is invested at the end of year 1). The interest rate is 10% annual compounded annually.
1) Investment X for 100,000 is invested at a nominal rate of interest, j, convertible semi-annually. After four years, it accumulates to 214,358.88. Investment Y for 100,000 is invested at a nominal rate of discount, k, convertible quarterly. After two years, it accumulates to 232,305.73. Investment Z for 100,000 is invested at an annual effective rate of interest equal to j in year one and an annual effective rate of discount equal to k in year two. Calculate the value...
