Textbook Question
Chapter 11.6, Problem 7CC
You are working for a tire manufacturer, producing wire to be used in the tire as a strengthening agent. You are considering implementing a new machining system, and you must present a breakeven analysis to your boss. You develop the graph, showing two possible machines that you can buy.
- a. Which machine has a higher fixed cost?
- b. Which machine has a lower variable cost?
- c. How much wire must be produced on Machine 1 to break even?
- d. If you make 3 million feet of wire, which machine will yield the higher profit?
- e. Which machine has the lower breakeven point?

In a manufacturing company, the routing of part A is started from machine X, and continued by machine Y, and then machine Z, and 23,000
parts must be produced per month. The routing of part B is machine Y, Z, and X, respectively, and 31,000 parts must be produced per
month. Set up time for machine X, Y, and Z are 35, 55, and 45 minutes, respectively. If the company works 6 days a week, four weeks a
month, 10 hours a day, with 45 minutes lunch break and two breaks of 20 minutes, and given the following information.
