Imperial Devices (ID) has offered to supply the state government with one model of its security screening device at "cost plus 20 percent." ID operates a manufacturing plant that can produce 22,000 devices per year, but it normally produces 20,000. The costs to produce 20,000 devices follow:

	Total Cost				Cost per Device
Production costs:
Materials	$	1,260,000			$	63.00
Labor		1,800,000				90.00
Supplies and other costs that will vary with production		860,000				43.00
Indirect cost that will not vary with production		640,000				32.00
Variable marketing costs		1,520,000				76.00
Administrative costs (will not vary with production)		1,260,000				63.00
Totals	$	7,340,000			$	367.00

Based on these data, company management expects to receive $440.40 (= $367.00 120 percent) per monitor for those sold on this contract. After completing 2,000 monitors, the company sent a bill (invoice) to the government for $880,800 (= 2,000 monitors $440.40 per monitor).

The president of the company received a call from a state auditor, who stated that the per monitor cost should be:

Materials	$	63.00
Labor		90.00
Supplies and other costs that will vary with production		43.00
	$	196.00

Therefore, the price per monitor should be $235.20 (= $196.00 120 percent). The state government ignored marketing costs because the contract bypassed the usual selling channels.

Required:

For each of the four situations, calculate the cost basis per device based on the information shown above. (Round intermediate calculations and final answers to 2 decimal places.)

Options:

A. Only the differential production costs could be considered as the cost basis.

B. The total cost per device for normal production of 20,000 devices could be used as the cost basis.

C. The total cost per device for production of 22,000 devices, excluding marketing costs, could be used as the cost basis.

D. The total cost per device for production of 22,000 devices, including marketing costs, could be used as the cost basis.
