Executive Summary:
Five Star Tools is a small family-owned business that manufactures diamond-coated cutting tools (chisels and saws) used by jewelers. The production of these tools involves three major processes. The first of these processes involves steel “blanks” (tools without the diamond coating) that are cut to size.

The benefit of gaining one more hrs of production time in coating and sharpening is illustrated in the contribution margin per hr.

Contribution margin per hour $1,250 ($250*5) $537.50 (430*1.25)

Management estimates that this action will free up 240 hrs in coating and sharpening (an average of 5 mins/hr * 8 hrs /day*360 operating days/yr)/60. Management has calculated the average contribution margin per unit for its products is $300. The average contribution margin per/hr spent coating and sharpening is $850.
Since the average contribution margin /hr spent sharpening and coating is $850 and the inspection station would save 240hrs. The company would generate $850*240 = $204,000 in profits.
