Weston Corporation manufactures a product that is available in both a deluxe and a regular model. The company has made the regular model for years, the deluxe model was introduced several years ago to tap a new segment of the market.

Sales of the deluxe model have been increasing rapidly Overhead is applied to products on the basis of direct labor-hours. At the beginning of the current year, management estimated that $2,520,000 in overhead costs would be incurred and the company would produce and sell 10,000 units of the deluxe model and 40,000 units of the regular model. The deluxe model requires 2.0 hours of direct labor time per unit, and the regular model requires 1.0 hour.
