The university has an ongoing community project in which it uses a machine in its mechanical engineering lab to provide an investment income for the university.
The machine can produce 100 widgets per hour. The lab operates 12 hours per day, five days per week. Due to regularly scheduled preventive maintenance, the lab expects the machine to be running during approximately 95% of the available time. Based on experience with other products, the lab expects to achieve an efficiency level for the widgets of 85%.
What is the expected weekly output of widgets for this lab

- Save Charles Lackey operates a bakery in Idaho Falls, Idaho Because of its excellent product and excellent location, demand has increased by 25% in the last year. On far too many occasions, customers have not been able to purchase the bread of their choice. Because of the size of the store, no new ovens can be added At a staff meeting, one employee suggested ways to load the ovens differently so that more loaves of bread can be boked at one time. This new process will require that the overs Employees are paid $8 per hour. In addition to the labor cost, Charles also has a constant utility cost per month of $550 and a per loaf ingredient cost of $0.50 loaded by hand, requiring additional manpower. This is the only production change that will be made in order to meet the increased demand.
