Daigo Dojima recently invested $5,500 in a project that is promising to return 2.25 percent per year. The cash flows are expected to be as follows: End of Year Cash Flow 1 $1000 2 $950 3 $875 4 ??? 5 $850 Note that the 4th year cash flow is unknown. Assuming the present value of this cash flow stream is $7,500 (that is, CF0 = -7500), what is the missing cash flow value (that is, what is the cash flow at the end of the 4th year)?
