Answer:
The effect on Morgantown's overall profit is $140,000 decrease in Morgantown's profits
Explanation:
In order to calculate the effect on Morgantown's overall profit we would have to make the following calculations:
Contribution margin per unit for Lock Division = Selling price – Variable costs = $40 - $22 = $18
Contribution lost by lock division if Cabinet division buys from outside = $18 * 10,000 = $180,000
Cost per unit saved by Cabinet division = $40 - $36 = $4
Total cost saved by cabinet division = $4 * 10,000 = $40,000
Net decrease in profit = Contribution lost – Cost saved = $180,000 - $40,000 = $140,000
Therefore, the effect on Morgantown's overall profit is $140,000 decrease in Morgantown's profits.
