Question 1 For question 1, use the following cash flows for projects A and B: A: (-$2,000, $500, $600 $700, $800) B: (-$2,000, $950, $850, $400, $300) (1.1) Calculate the payback period for projects A and EB. If the discount rate is 12%, what is the discounted payback period for project A? For Project B? (12) (1.3) Calculate the internal rate of return for projects A and B. If A and B are mutually exclusive projects and the required rate of return is 5%, which should be accepted? (1.4)
