An oil refinery finds that it is necessary to treat the waste liquids from a new process before discharging them into a stream. In-house treatment will have an annual cost of $30,000 the first year, but process improvements will allow the cost to decline by $3,000 each subsequent year. As an alternative, an outside company will process the wastes for an initial cost of $15,200 and an annual fixed price of $13,200/year throughout the 10 year period. Either way, there is need to treat the wastes after 10 years. Using the AW method, calculate the equivalent uniform annual cost (EUAC) of each alternative and determine how the waste should be processed. The company's MARR is 10%. Click the icon to view the interest and annuity table for discrete compounding when the MARR is 10% per year.
