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 this 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 requrie that the ovens be, loaded by hand, requiring additional manpower. This is the only production change that will be made in order to meet the increased demand. The bakery currently makes 1,600 loaves per month. Employees are paid $8 per hour. In addition to the labor cost, Charles also has a constant utility cost per month of $700 and a per loaf ingredient cost of $0.50.
Current multifactor productivity for 640 work hours per month= .242 loaves/dollar (round your response to three decimal places).

(Hint: Each worker works 160 hours per month.) If the bakery currently makes 1,500 loaves per month with a labor productivity of 2.344 loaves per labor hour, then Lackey will need to add 4 worker(s) to meet the increased demand (recall that each worker works 160 hours per month and round your response up to the next whole number).arrow_forward
