Suppose you were shown a project with the following cash flows: Year 0 Year 1 Year 2 Year 3 Year 4 Cash Flow -$14,050 $7,800 (in $) - $500 -$500 $15,000 In assessing this project using the internal rate of return, your most pressing concern should be: that the IRR rule cannot handle future cash flows that are of unequal amounts. that multiple IRRs may exist for the project. that the payback period rule and internal rate of return rule for the project disagree with one another. that a cost of capital for the project might not exist
