Assume the yearly cash flows from a $50,000,2-year investment are $30,000 at the end of year 1 and $40,000 at the end of year 2 , and the discount rate is 10%. The discount rate equals the IRR when which of the following equations hold true? 30,000/(1+r)1+40,000/(1+r)2=030,000/(1+r)1+40,000/(1+r)2=0.1070,000/(1+r)2=030,000/(1+r)1+40,000/(1+r)250,000=0
