I need help for the below

Members of the board of directors of Control One have received the following operating Income data for the year ended May 31. 2014:

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 $83,000 and decrease fixed selling and administrative expenses by $10,000.

Requirements

1. Prepare a differential analysis to show whether Control One should drop the industrial systems product line
2. Prepare contribution margin income statements to show Control Ones total operating income under the two alternative (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.
3. What have you learned from the comparison in Requirement 2?
