5. The analysis period is infinite at the annual interest rate of 10%. Initial machine cost $400,000 Annual maintenance costs 20,000 Annual benefits 150,000 Life 20 years It is assumed to replace the machine every 20 years at $400,000 for an infinite period. The annual maintenance costs and benefits will be changed as follows: Annual maintenance costs increase $1,000 every year after the first year for the useful o Annual benefits decrease $5,000 every year after the first year for the useful life period Calculate the equivalent uniform annual benefit (EUAB) and equivalent uniform annual cost life period (EUAC).
