The risks of the projects often differ significantly, from very little risk to risks that are substantially greater than the average risk associated with the firm. If Express Press always uses its weighted average cost of capital, or average required rate of return, to evaluate all of these capital budgeting projects, then the company might make an incorrect decision, or a mistake, by a. accepting projects that actually should be rejected. b. accepting projects with internal rates of return that are too high. c. rejecting projects that actually should be rejected. d. rejecting projects with internal rates of return that are lower than the appropriate risk-adjusted required rate of return. e. accepting project that actually should be accepted
