Final answer:
Accepting the special order would decrease the net income by $55,000.
Step-by-step explanation:
To determine the effect on net income if the special order is accepted, we need to compare the profit before and after accepting the order. Currently, the company's profit per unit is $38 - $26 = $12. If the special order is accepted, the profit per unit will be $21 - $18 - $2 = $1.
The company would produce 5000 units, so the total profit before accepting the order would be $12 x 5000 = $60,000. After accepting the order, the total profit would be $1 x 5000 = $5000.Therefore, accepting the special order would decrease the net income by $60,000 - $5000 = $55,000.
