[ Select] 1 pts Question 4 Question 3 1 pts 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 baked at one time. This new process will require that the ovens be loaded by hand, requiring additional manpower. This is the only thing to be changed. The bakery currently makes 1,800 loaves per month. The pay will be $8 per hour for employees and each employee works 160 hours per month. Charles Lackey can also improve the yield by purchasing a new blender.
