A $500,000 SMP investment is being considered. It is anticipated that annual savings of $92,5000 will result from the investment. A salvage value of $50,000 is expected at the end of the 10-yr planning horizon. The MARR is 10%. Analyze the sensitivity of annual worth to errors in estimating (1) the initial investment, (2) the annual savings, (3) the salvage value, (4) the duration of the investment, and (5) the MARR. Specifically, consider an error range of +50% AW (10%) = $500,000(A/P 10%, 10) + $50,000(A/F 10 %, 10) + $92,500
