The Dubs Division of Fast Company (the parent company) produces wheels for off-road sport vehicles. Dubs has two products, 1 and 2. The two products only differ in how they are marketed. Product 1 is sold in bulk to customizing shops, while Product 2 is sold directly to consumers. Dub's estimated operating data for the year follows. Product 1: Revenues ... $300,000; Var Mfg ... $160,000; Var G&A ... $40,000; CM ... $100,000; Fixed Mfg ... $24,000; Fixed G&A ... $36,000; Op. Profits ... $40,000; Unit Sales ... 1,000. Product 2: Revenues ... $400,000; Var Mfg ... $160,000; Var G&A ... $60,000; CM ... $180,000; Fixed Mfg ... $32,000; Fixed G&A ... $48,000; Op. Profits ... $100,000; Unit Sales ... 1,000. Unless otherwise stated assume the fixed costs given above are allocated costs and unavoidable. Currently the Dubs division has a total manufacturing capacity of 2,000 wheels per year. If the maximum external demand for either product separately is 1,500 units, how much would profits increase if two additional production workers were added? The new workers would not change the per unit variable manufacturing costs of either product. However, they would add a total of $20,000 in annual fixed manufacturing costs and increase capacity by 300 wheels (in total). Assume Dubs uses the additional capacity to maximize total profits, but also produces at least 1,000 units each of Product 1 and Product 2 .
