D months (Round to four decimal places.) Wally, president of Wally's Burgers, is considering franchising. He has a potential franchise agreement that would allow him to receive 13 end-of-year payments starting one year from now. The rst two payments would be 827,000 and $22,000 in one and two years respectively, and then $19,000 per year after that for 11 years. If Wally requires a return of 9.4%, what is the present value of this stream of cash ows? What is the present value of this stream of cash ows? $|:| (Round to the nearest cent.)
