A machine costs $17,940 and is expected to have a scrap value of $2,711 whenever it is retired. Operating and Maintenance costs are $1,597 for the first year and expected to increase by $1,545 thereafter. If the MARR is 10%, determine the minimum equivalent uniform annual cost associated with the optimal economic life of the machine. The service life of this machine is 5 years. Note: round your answer to two decimal places, and do not include spaces, currency signs, plus or minus signs, nor commas.
