Robinson Manufacturing Corporation makes an electronic component in two departments, Machining and Assembly. The capacity per month is 100,000 units in the Machining Department and 150,000 units in the Assembly Department. The only variable cost of the product is direct material of $300 per unit. All direct material cost is incurred in the Machining Department. All other costs of operating the two departments are fixed costs. Robinson can sell as many units of this electronic component as it produces at a selling price of $500 per unit. Required: a) Robinsons Machining managers believe that they could increase the capacity in their department by 20,000 units, if they were able to increase fixed costs by $5,000,000. Should the money be spent? Explain. b) An outside contractor offers to do assembly for 20,000 units at a cost of $1,600,000. Should Robinson accept the offer from the subcontractor? Show calculations. c) How do your answers in parts (a) and (b) relate to the theory of constraints? Explain
