Members of the board are surprised that the industrial systems product line is losing money. They commission a study to determine whether the company should discontinue the line. Company accountants estimate that dropping industrial systems will decrease the fixed cost of goods sold by $82,000 and decrease fixed selling and administrative expenses by $15,000.

Required:
a. Prepare a differential analysis to show whether Safety Step should drop the industrial systems product line.
b. Prepare contribution margin income statements to show Safety Step's total operating income under the two alternatives: (a) with the industrial systems line and (b) without the line. Compare the difference between the two alternatives' income numbers to your answer to Requirement 1.
c. What have you learned from the comparison in Requirement 2?
