Please help with question 8,9&10

RELIABILITY

A certain company produces 8,000 tables per year in a three-step process. The cost to produce one table is $135.

The three steps in the process employ machines with the reliabilities listed here: Step A: 0.985 Step B: 0.980 Step C: 0.860

Question #8

The company can choose to buy a back-up machine for Step C for an additional $27,000. The back-up would also have a reliability of 0.860, just like the one that is presently used. If they decide to get this back-up machine, what will the new reliability of the system be? Assume that once a machine malfunctions, the process continues to produce product, acceptable and defective. THREE decimal places.

Question #9

With the back up in place, how many defects will the process produce annually given the same demand rate?

Question #10

How much do they stand to save this year if the cost of the back-up machine is included in your calculation? Remember to include the cost of the back-up into your calculations.
