a final exam on the last day of exam week, and she is leav-ing town the same day. She is concerned about her ability to
finish grading her exams. She estimates that with every-thing else she has to do she has only five hours to grade the
exams. From past experience she knows the first exam will

- The Toys-R-U Company has developed two new toys for possible inclusion in its product line for the upcoming Christmas season. Setting up the production facilities to begin production would cost $50,000 for toy1 and $80,000 for toy 2. Once these costs are covered, the toys would generate a unit profit of $10 for toy 1 and $15 for toy 2. The company has two factories that are capable of producing these toys. However, to avoid doubling the start-up costs, just one factory would be used, where the choice would be based on maximizing profit. For administrative reasons, the same factory would be used for both new toys if both are produced. Toy 1 can be produced at the rate of 50 per hour in factory 1 and 40 per hour in factory 2. Toy 2 can be produced at the rate of 40 per hour in factory 1 and 25 per hour in factory 2. Factory 1 and 2, respectively, have 500 hours and 700 hours of production time available before Christmas that could be used to produce these toys.

In order to meet the Christmas demand, the company is considering employing an additional five hundred and fifty (550) workers and establishing a shift system. The first shift will work from 8 a.m. to 3 p.m. and the second shift from 3. p.m. to 11 p.m. Management took a decision not to pay a shift premium but told the workers in a meeting that they will be given a bonus at the end of the year providing the set targets are achieved. The workers were unhappy with the outcome of the meeting and decided to discuss the matter with their trade union. A delegation from the union met with management and the meeting ended in a stalemate. A second meeting was set to resolve the conflict. Prior to that meeting, management met and agreed that their position is right and they are not going to change. At the second meeting, both teams held their…arrow_forward
