Suppose we have four mutually exclusive projects, D1, D2, D3, and D4, whose internal rates of return on incremental investment between the projects is given as follows:IRR (Dl - D2) = 27.62%IRR {Dl - D3) = 14.26%IRR {Dl - D4) = 25.24%IRR (D3 - D2) = 30.24%IRR (D2- D4) = 17.34%IRR (D3 - D4) = 16.14%Which project should be selected at MARR 15%?
Consider the two investments with the following sequences of cash flows
Compute for i* for each investment
What are the NPW of each alternatives with an MARR of 15%
If A & B are mutually exclusive, which project is more economically desirable? (Incremental)
Three investments are being studied by Bright Star Construction Limited. The table below provides the
estimated cash flow for each of the three investments over the next five years. Due to budget constraints,
Bright Star can only select one investment out of the three investments. At a MARR (Minimum Acceptable
Rate of Return) of 12%, answer the following.

In this method the annual cash flows under the alternative investments are converted into a constant cash flow stream whose NPV is equivalent to the NPV of the comparative project's Initial stream. Consider the case of Three Waters Boatbuilders: Three Waters Boatbuilders is considering a three-year project that has a weighted average cost of capital of 10% and a net present value (NPV) of $85,647. Three Waters Boatbuilders can replicate this project indefinitely. The equivalent annual annuity (EAA) for this project is The EAA approach to evaluating projects with unequal lives does not do a good job of taking inflation into account.arrow_forward
