A certain engine lathe can be purchased for $210,000 and depreciated over three years to a zero salvage value with the SL method. This machine will produce metal parts that will generate revenues of $140,000 (time zero dollars) per year. It is a policy of the company that the annual revenues will be increased each year to keep pace with the general inflation rate, which is expected to average 3.5% per year. Labor, materials, and utilities totaling $35,000 (time 0 dollars) per year are all expected to increase at 6% per year. The firm's effective income tax rate is 48%, and its after-tax MARR (i_m) is 18% per year. Determine the after-tax equivalent present worth. Use life of three years and work to the nearest dollar. (Do not enter the dollar sign exist with your answer.)
