Estimates for one of two process upgrades are as follows first cost of $40,000, annual cost of $5000 per year, market value that decreases by S2000 per year to the salvage value of $20,000 after the expected life of 10 years. If a 4-year study period is used for AW analysis at 15% per year, the correct AW value is closest to 5-15.000 Co 5.11.900 OS$7.600 d. -12,602
