There are three factories I, II, and III that each produce the same two types of pollutants (1 and 2). The waste from each factory can be treated to reduce the tons ofpollutants being emitted. For Factory I it costs $15 per ton to reduce pollutant 1 by 0.10 ton and pollutant 2 by 0.45 ton. For Factory II it costs $10 per ton for similarreductions of 0.10 of pollutant 1 and 0.25 of pollutant 2. For $ 20 per ton the figures for Factory III are 0.40 for pollutant 1 and 0.30 for pollutant 2.The state requires an overall reduction of 42 tons of pollutant 1 and 56 tons of pollutant 2. In order to achieve this goal with minimum cost the state will choose thefollowing values:Set up the LP and then solve with softwareTons of Factory I processed =Tons of Factory Il processed =Tons of Factory III processd =

Use the following for the next 2 questions: A company forecasts that it will ship 120,000 boxes of product in June. The product has a monthly turnover of 3. The company plans to use its facility to ship 80,000 boxes and the balance of the 40,000 boxes will ship from a rented facility. Space may be rented for a charge of $7 per box per month with an in-and-out handling charge of $0.45 per box shipped. 1. What is the rented (fixed) storage cost for June? - $280,000 - $180,000 - $42,500 - $250,000 - $93,333 - $153,333 - $173,333 2. What is the rented variable cost for June? - $33,333 - $43,333 - $6,000 - $38,000 - $18,000 - $28,000 - $23,333
A series of thefts from your pharmacy area have occurred in the last six weeks. The director of security and the head of pharmacy services now require all persons working in the pharmacy department with access to drugs to clock out after their shifts and then go through a security check before leaving the building. Several employees have complained that they should be paid for this time because the security check is for the employer’s benefit. The director of security and the head of pharmacy services have responded that this security check is for the benefit of the employees to ensure that no one is unjustly accused. Is either party correct? If so, which one and why?
Some citizens complained to city council members that there should be equal protection under the law against the occurrence of crimes. The citizens argued that this equal protection should be interpreted as indicating that high-crime areas should have more police protection than low-crime areas. Therefore, police patrols and other methods for preventing crime (such as street lighting or cleaning up abandoned areas and buildings) should be used proportionately to crime occurrence. The city has been broken down into 20 geographic areas, each containing 5,000 residences. The police recognize that not all crimes and offenses are reported: people do not want to become involved, consider the offenses too small to report, are too embarrassed to make a police report, or do not take the time, among other reasons. Every month, because of this, the police are contacting by phone a random sample of 1,000 of the 5,000 residences for data on crime. (Respondents are guaranteed anonymity.) The 1,000…
A suburb of Dayton, Ohio, has four local dry cleaners that compete with each other on the basis of price and service speed. Each of them can perform the same basic services at the same level of quality. The following table provides the price that each dry cleaner charges to clean a two-piece suit, as well as the quoted number of days that the service will take. Dry Cleaner Price Number of Days A $ 8.00 3 B $ 9.50 3 C $ 9.00 2 D $ 7.50 4 Which of these dry cleaners are NOT on the efficient frontier?
The Woodruff Corporation purchased a piece of equipment three years ago for $211,000. It has an asset depreciation range (ADR) midpoint of eight years. The old equipment can be sold for $89,000. A new piece of equipment can be purchased for $321,500. It also has an ADR of eight years.

Sturgill Manufacturing Inc. needs to predict the numbers of machines and employees required to produce its planned production for the coming year. The plant runs three shifts continuously during the workweek, for a total of 120 hours of capacity per week. The shop efficiency (the percent of total time available for production), which accounts for setups, changeovers, and maintenance, averages 70% with a standard deviation of 5%, which reduces the weekly capacity. Six key parts are produced, and the plant has three different types of machines to produce each part. The machines are not interchangeable as they each have a specific function. The time to produce each part on each machine varies. The mean time and standard deviation (in hours) to produce each part on each machine are shown below: Mean Time Part Type Machine A Machine B Machine C 1 3.5 2.6 8.9 2 3.4 2.5 8 3 1.8 3.5 12.6 4 2.4 5.8 12.5 5 4.2 4.3 28 6…

Assume that only purchasing costs are being considered. Compute the total processing time required for each machine type to meet demand, how many of each machine type would be needed, and the resulting total purchasing cost for each machine type.
