Smith and Co. has to choose between two mutually exclusive projects. If it chooses project A, Smith and Co. will have the opportunity to make a similar investment in three years. However, if it chooses project B, it will not have the opportunity to make a second investment. The following table lists the cash flows for these projects. If the firm uses the replacement chain (common life) approach, what will be the difference between the net present value (NPV) of project A and project B, assuming that both projects have a weighted average cost of capital of 10%?

Smith and Co. is considering a three-year project that has a weighted average cost of capital…
Consider the two mutually exclusive projects described in the table below. (Note: Each part of the question requires a
written answer.)
a) Assuming 9% minimum attractive rate of return (MARR), should either of the two projects be accepted?
Why?
b) Assuming 16% MARR, should either of the two projects be accepted? Why?
c)
For any positive value of the MARR, divide the possible MARR values into ranges with different decisions;
describe and discuss what decision would be made in each range and why. You will need to calculate the
crossover rate to determine the precise MARR where the decision changes. Include an NPV profile table and
chart to illustrate your answer.
