please explain how to solve for option D

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 Labor Supplies and other costs that will vary with production Indirect cost that will not vary with production Variable marketing costs Administrative costs will not vary with production) Totals $ 1,060,000 1,680,000 760,000 700,000 1,320,000 1.320.00 3340.000 $ 53.00 34.00 38.00 35.00 91.00 66.00 5167.00 Based on these data, company management expects to receive $440.40 - $36700 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 $53.00 Materials Labor Supplies and other costs that will vary with production 14.00 38.00 $175.00 Therefore, the price per monitor should be $210.00 = $175.00 X 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. Answer is complete but not entirely correct. Per device Recommended cost basis price per device Option A S 175 00 3 210.00 Option B S 367 00 $ 44040 Option S 206 82 $ 320.18 Option D S 333 4 5 410 46
