Charles Lackey operates a bakery in Idaho Falls, Idaho. Because of its excellent product and excellent location, demand has increased by $45\%$ 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 moce loaves of bread can be baked at one time. This new process will require that the ovens be loaded by hand, requing additional marpower. This is the only production change that will be made in order to meet the increased demand. The bakery currently makes $1,800$ loawes per month. Employee paid $$8$ per hour. In addition to the labor cost, Charles also has a constant utility cost per month of $$800$ and a per loaf ingredient cost of $$0\mathrm{.}35.$
