Bernard's Books produces 50,000 books per month, which is 80% of plant capacity. Variable manufacturing costs are $4 per unit. Fixed manufacturing costs are $200,000, or $2 per unit. The books are normally sold direct to publishers for $10 each. Bernard has an offer from Laura's Literature to purchase an additional 1,000 books at $6 per unit. Acceptance of the offer would not affect normal sales of the product, and the additional units can be manufactured without affecting plant capacity. How much would accepting the special order at a special price increase or decrease Bernard's net income
