Draw cash flow diagrams for all problems. The following cash flow is given List all possible rates of return for this cash flow. For the cash flow from problem #1, the MARR is 20% and the external rate is 15%. What is the modified rate of return for the project? Is this project worth doing using ROR as a measure of goodness? For the cash flow from problem #1, the MARR is 20%. Is this project worth doing using PW as a measure of goodness? Create a cash flow that has rates of return of 8%, 12%, and 22%. The following cash flows are expected for two independent projects: Assume that the lowest MARR is 0% and PW is the measure of goodness. For what range of MARR is project A preferable to B For what range of MARR is project B preferable to A
