Unless otherwise stated, assume a regular selling price of $380 per unit. Ignore income taxes and other costs that are not mentioned in the table or in the question itself. Complete this question by entering your answers in the tabs below. Req A1 Req A2 Req B Reqc Reg D Req E1 Req E2 Req F1 Req F2 A proposal is received from an outside contractor who will make and ship 2,000 stoves per month directly to Davis's customers as orders are received from Davis's sales force. Davis's fixed marketing costs would be unaffected, but its variable marketing costs would be cut by 20 percent for these 2,000 units produced by the contractor. Davis's plant would operate at two-thirds of its normal level, and total fixed manufacturing costs would be cut by 20 percent. What in-house unit cost should be used to compare with the quotation received from the supplier? Assume the payment to the outside contractor is $220. (Round your answer to 2 decimal places.)
