Deru Chocolate Company manufactures two popular candy bars, the Venus bar and the Comet bar. Both candy bars go through a mixing operation where the various ingredients are combined, and the Coating Department where the bars from the Mixing Department are coated with chocolate. The Venus bar is coated with both white and dark chocolate to produce a swirled effect. A material shortage of an ingredient in the Comet bar limits production to 300 batches per day. Production and sales data are presented in the following table. Both candy bars are produced in batches of 200 bars.

	Use of Capacity in Hours per Batch of Product
Department	Available Daily Capacity in Hours		Venus		Comet
Mixing		525				1.5				1.5
Coating		500				2.0				1.0

Management believes that Deru Chocolate can sell all of its daily production of both the Venus and Comet bars. Other data follow.

	Venus	Comet
Selling price per batch		$	300			$	350
Variable cost per batch			100				225
Monthly fixed costs (allocated evenly between both products)			375,000				375,000

Required: 1. Complete the following equations for the objective function and all of the constraints in order to maximize contribution margin. 2. How many batches of each type of candy bar (Venus and Comet) should be produced to maximize the total contribution margin? 3. Calculate the contribution margin at the optimal solution.
