General Electric manufactures two types of refrigerators: 1-Door and 2-Door. Selected data related to each type of refrigerator is as follows:

	1-Door		2-Door
Sales price	$300		$400
Direct materials	25		50
Direct labor	30		40
Variable overhead	15		10
Machine hours	5		6

Total fixed manufacturing overhead is $500,000. Most of the manufacturing process is done by machines. For 2023, there is a maximum of 20,000 machine hours available. Management believes that demand is limited to 2,000 1-Door refrigerators and 3,000 2-Door refrigerators in 2023.

At the optimum solution (constrained by 20,000 MHs), what is the total contribution margin from selling 1-Door and 2-Door refrigerators?
