Daigo Dojima recently invested $5600 in a project that is promising to return 3.785 percent per year. The cash flows are expected to be as follows: End of Year 1 2 3 Cash Flow $1000 950 875 ??? 850 4 5 Note that the 4th year cash flow is unknown. Assuming the present value of this cash flow stream is $5600 (that is, CF0=-5600), what is the missing cash flow value (that is, what is the cash flow at the end of the 4th year)?
