1.13 Charles Lackey operates a bakery in Idaho Falls, Idaho.Because of its excellent product and excellent location, demand hasincreased by 25% in the last year. On far too many occasions, customershave not been able to purchase the bread of their choice.Because of the size of the store, no new ovens can be added. At astaff meeting, one employee suggested ways to load the ovens differentlyso that more loaves of bread can be baked at one time. Thisnew process will require that the ovens be loaded by hand, requiringadditional manpower. This is the only thing to be changed. If thebakery makes 1,500 loaves per month with a labor productivity of2.344 loaves per labor-hour, how many workers will Lackey need toadd? (Hint: Each worker works 160 hours per month.)
