An electronics firm is currently manufacturing an item that has a variable cost of $.50 per unit and a selling price of $1.00 per unit. Fixed costs are $14,000 per month. Current demand volume is 360,000 units per year. The firm can substantially improve the product quality by adding a new piece of equipment at an additional monthly fixed cost of $6,000. Variable cost would also increase to $.60 per unit, but annual demand volume is also expected to jump to 600,000 units due to the improved product quality. a. Based on the above information, determine whether the addition of the new equipment is a profitable proposition for the company. b. What is the minimum unit price that would render profitable the addition of the new equipment? Demonstrate clearly all the calculations that support your answers to the above questions.
