The Immanuel Company has just obtained a request for a special order of 6,000 jigs to be shipped at the end of the month at a selling price of $7 each. The company has a production capacity of 90,000 jigs per month with total fixed production costs of $144,000. At present, the company is selling 80,000 jigs per month through regular channels at a selling price of $11 each. For these regular sales, the cost for one jig is:$\begin{array}{|l|r|}
\hline \text { Variable Production Cost } & \$ 4.60 \
\hline \text { Fixed Production Cost } & \$ 1.80 \
\hline \text { Variable Selling Expense } & \$ 1.00 \
\hline
\end{array}$
If the special order is accepted, Immanuel will not incur any selling expense; however, it will incur shipping costs of $\$ 0.30$ per unit.
-Suppose that total regular sales of jigs are 85,000 units per month,and all other conditions remain the same.If Immanuel accepts the special order,what will be the change in monthly operating income?
A) $3,600 decrease.
B) $5,400 decrease.
C) $7,200 increase.
D) $14,000 increase.

The special order's contribution margin per unit is calculated by subtracting the variable costs from the selling price. The variable costs include the variable production cost of $4.60 and the shipping cost of $0.30, totaling $4.90. The selling price is $7, so the contribution margin per unit is $7 - $4.90 = $2.10. For 6,000 units, the total contribution to operating income is 6,000 * $2.10 = $12,600.However, accepting the special order increases total sales to 85,000 units, which exceeds the company's regular sales of 80,000 units. The fixed production costs are spread over more units, reducing the fixed cost per unit for all units sold. But since the fixed production costs are a total amount ($144,000) and do not change with the number of units produced (up to the capacity limit), the calculation of the change in operating income only needs to consider the additional contribution margin from the special order.Therefore, the correct answer is that accepting the special order will result in a $12,600 increase in monthly operating income, which is not an option provided. Given the options, the closest correct interpretation based on the provided information would be to reevaluate the calculation or the interpretation of the options. Given the error in initial calculation and interpretation, the correct approach is to calculate the additional contribution from the special order without considering changes in fixed costs (since they remain constant and are already accounted for in the per-unit cost) and without incorrectly adjusting for overcapacity, which was not a factor in the original question. The mistake was in the interpretation of the effect of the special order on fixed costs and the misapplication of the contribution margin calculation.
