Three Point Sports Inc. manufactures basketballs for the Women's National Basketball Association (WNBA). For the first 6 months of 2017, the company reported the following operating results while operating at 80% of plant capacity and producing 119,400 units:
Sales $4,656,600
Cost of goods sold 3,684,708
Selling and administrative expenses 526,292
Net income $445,600
Fixed costs for the period were cost of goods sold $ 960,000 and selling and administrative expenses $ 266,000.
In July, normally a slack manufacturing month, Three Point Sports receives a special order for 10,000 basketballs at $ 28 each from the Greek Basketball Association (GBA).
Acceptance of the order would increase variable selling and administrative expenses by $ 0.77 per unit because of shipping costs but would not increase fixed costs and expenses.
Required:
(a) Prepare an incremental analysis for the special order.
