QUESTION 4 A corporation purchased a machine for $60,000 five years ago. It had an estimated life of 10 years and an estimated salvage value of $9,000. The current book value of this machine is $7,500. If the current market value is $25,000 and the effective income tax rate is 44%, what is the after-tax investment value (rounded to the nearest whole dollar) of the machine? Use the outsider viewpoint. The after-tax MARR is 10% per year. (Do not enter the dollar sign $ with your answer.)
