Sunbeam Corporation manufactures gas grills. Next year's production is expected to be 20,000 units of Model Q. Currently, the company manufactures a searing attachment to cook steaks. One searing attachment is required for each Model Q grill. Sunbeam has received an offer from a vendor to supply any number of searing attachments at $15.00 per grill. This year's production costs were prepared by the accounting intern, a reliable EMU student.
