50-kilowatt gas turbine has an investment cost of $57,000. The operation and maintenance expense for this turbine is $400 per year. Additionally, the hourly fuel expense for running the turbine is $7.50 per hour, and the turbine is expected to operate 4,000 hours each year. The cost of dismantling and disposing of the turbine at the end of its 8-year life is $8,000. If the MARR is 15% per year, what is the annual equivalent life-cycle cost of the gas turbine? Please only fill in the number of your calculated result in the blank, e.g., if the result is $100, fill in "100"; also round to the nearest integer. Note "cost" should be a negative number.
