Members of the board are surprised that the industrial systems product line is not profitable. They commission a study to determine whether the company should drop the line. Company accountants estimate that dropping industrial systems will decrease fixed cost of goods sold by $82,000 and decrease fixed selling and administrative expenses by $10,000.
