Charles Lackey opiates a bakery in Idaho Falls, Idaho. Because of its excellent location, demand has increased by 25% in the last year. On far too many occasions, customers have not been able to purchase the bred 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 baked at one time. This new process will require that the ovens be loaded by hand, requiring additional man power. This is the only production change that will be made in order to meet the increased demand. The bakery currently makes 1800 loaves per month. Employees are paid $8 dollars an hour. In addition to the labor cost, Charles also has a constant utility cost per month of $650 and per loaf ingredient cost of $0.50
