Table #1. Investment and Revenues for machines A and B
a. Evaluate the data presented and decide which is a better purchase in terms of payback period, net present value (use 10 percent) and internal rate of return.
#2. Banks A and B advertise different interest rates. Bank A pays a nominal rate of 5% per year compounded monthly, and Bank B pays depositors 4 ¾% per year compounded daily. Which bank has a better rate and why?
#3. A project engineer has produced the estimates (in millions of dollars) presented in Table 2. Find the expected cost of the project.
