A maker of mechanical systems can reduce product recalls by 25% if it purchases new packaging equipment. The cost of the new equipment is expected to be $40,000 four years from now. How much could the company afford to spend now, instead of 4 years from now, if it uses a minimum attractive rate of return of 12% per year?

Suppose you were considering purchasing a $5000 machine today that would generate additional net profit of $2000 booked at the end of each year.  Assuming you need a 15 percent return to justify the investment, would the investment be worth doing if you had only three years of payouts?  Would your answer change if you had four years of $2000 payouts?  Why or why not?

Andes, Inc. is considering the replacement of its manual material handling equipment with autonomous vehicles at a net initial cost of $12 million. The expected annual savings in operating costs are as shown below. MARR is 10% per year compounded annually. End of Year 1 2 3 4 5 6 3 4.5 4.5 Annual savings (millions) | 2.25 | 2.25 | 3 Compute the simple payback period for this replacement option. Determine the discounted payback period (DPBP). It is enough if you determine in which year the DPBP falls.

You are considering buying a 10-year-old machine for $280, or a new fuel-efficient machine for$600.
