The analysis period is infinite at the annual interest rate of 10%. It is assumed to replace the machine every 20 years at $400,000 for an infinite period.

5. The analysis period is infinite at the annual interest rate of 10%. Initial machine cost Annual maintenance costs Annual benefits $400,000 20,000 150,000 Life 20 years It is assumed to replace the machine every 20 years at s400,000 for period. an in The annual maintenance costs and benefits will be changed as follows: Annual maintenance costs increase sl,000 every year the first year for the useful period Annual benefits decrease $5,000 every year after the first year for the useful life period Calculate the equivalent uniform annual benefit oEUAB) and equivalent uniform annual cost (15 points)
