Costs and reliability

Given the following, find the break-even point in $ and in units.
F = fixed cost = $1,000

V = variable cost = $2/unit

P = selling price = $4/unit
2. A product has three components, A, B, and C in series connection , with reliabilities of 0.95, 0.98, and 0.995. Engineers intend to put a backup component A that has reliability 0.70. With this change, will the system reliability decrease? What’s is the new reliability?

Complete the following problems
Jack’s Grocery is manufactures a “store brand” item that has a variable cost of $0.75 per unit and a selling price of $1.25 per unit. Fixed costs are $12,000. Current volume is 50,000 units. The Grocery can substantially improve the product quality by adding a new piece of equipment at an additional fixed cost of $5,000. Variable cost would increase to $1.00, but their volume should increase to 70,000 units due to the higher quality product. Should the company buy the new equipment?
