12-20 The firm’s marginal cost of capital is 14.61 percent. Thus, Project A (high-risk) should be evaluated
at a risk-adjusted cost of capital of 16.61 percent, while Project B (low-risk) should be evaluated at
12.61 percent. The average-risk projects (C and D) continue to be evaluated at 14.61 percent.
Now we have the following situation:
