Nguyen Medical Parts Industries currently manufactures 20,000 components internally each year for the medical equipment it assembles and sells. The total manufacturing cost of the components was determined as follows: Direct materials $100,000 Direct labor $160,000 Variable manufacturing overhead $60,000 Fixed manufacturing overhead $80,000 $5,000 of the fixed manufacturing overhead can be traced specifically to the manufacture of these components. An outside supplier has offered to sell the component to Nguyen for $17 per unit. If Nguyen purchases the component from the outside supplier, part of the manufacturing facilities would be unused and could be rented out for $10,000. If Nguyen purchases the component from the supplier instead of manufacturing it, by how much would income increase or decrease? Show your calculations clearly, especially the costs under the two different scenarios (make vs. buy). (6 points)
