Grocers Inc. is considering offering a purified water service through a contract company that would locate a machine on the inside of the market store. There are two contract companies Grocers Inc. is considering, ClearWater and PureVida. ClearWater would charge an annual lease fee of $800 for set-up of the machine and for this machine, there is a utility cost of $0.10 for every gallon of water dispensed and ClearWater charges $0.05 for maintenance. For PureVida, the annual lease fee is $700, the utility cost is $0.12 for every gallon and PureVida charges $0.06 for maintenance. Grocers Inc. customers would purchase refilled gallons of water for $0.97.a. What is the annual break-even point for each option?b. At what volume in number of gallons would the two options have the same cost?c. At what forecasted volume should Grocers Inc. select ClearWater and what volume should they select PureVida and why?

- 4.Silicon Valley Transport Commission (SVTC) has a fleet of maintenance vehicles that includes cars, vans, and trucks. SVTC is currently evaluating four different approaches to help them maintain their fleet of cars and vans efficiently at the lowest possible cost. Their options are: (1) No preventive maintenance at all and repair vehicle components when they fail; (2) Take oil samples at regular intervals and perform whatever preventive maintenance is indicated by the oil analysis; (3) Perform an oil change on a regular basis on each vehicle and perform repairs when needed; (4) perform oil changes at regular intervals, take oil samples regularly, and perform maintenance repairs as indicated by the sample analysis. Option #1 costs nothing to implement and results in two possible outcomes: There is a .10 probability that a defective component will occur, requiring emergency maintenance at a cost of $1,200, or there is a chance that no defects will occur and no maintenance will be…arrow_forwardProblems 2 Helen Murvis, hospital administrator for Portland General Hospital, is trying to determine whether to build a large wing onto the existing hospital, a small wing, or no wing at all. If the population of Portland continues to grow, a large wing could return $150,000 to the hospital each year. If the small wing were built, it would return S$60,000 to the hospital each year if the population continues to grow. If the population of Portland remains the same, the hospital would encounter a loss of $85,000 if the large wing were built. Furthermore, a loss of $45,000 would be realized if the small wing were constructed and the population remains the same. Unfortunately, Helen does not have any information about the future population of Portland * Develop a decision table for this problem. * Determine the best decision using the following decision criteria 1.
