Answer:
The sale of the machine will generate an after-tax income of 90,000
Explanation:
The company will be paying a tax income for the diference between the sales price and the book value at a rate of 40%
200,000 - 50,000 = 150,000 x 40% = 60,000 tax income
150,000 gross profit - 60,000 tax income = 90,000 net gain from sale of machine
