A company must make a choice between two investment alternatives. Alternative 1 will return the company $15,000 at the end of four years and $76,000 at the end of six years. Alternative 2 will return the company $8,500 at the end of each of the next six years. The company normally expects to earn a rate of return of 16% on funds invested. Compute the present value of each alternative and determine the preferred alternative according to the discounted cash flow criterion
