BARILLA SpA (A)‚ (C) and (D) 1. Draw a flow diagram for Barilla dry products sold through distributors. Your diagram will have four major sections: Barilla production‚ Barilla Finished Goods Inventory‚ Distribution Centers‚ and grocers. Indicate the flows of both physical goods and information. At appropriate places on your diagram‚ collect any relevant statistics mentioned in the case‚ for example on inventories‚ lead-times‚ etc. Please refer to the following page (page 2 of this document)

MBA 570 Homework Questions Chapter 1 and 2 Chapter 1 (1-20) Mysti Farris (See problem 1-19) is considering raising the selling price of each cue to $50 instead of $40. If this is done while the costs remain the same‚ what would the new breakeven point be? What would the total revenue be at this breakeven point? (Given in problem 1-19: fc of 2400 and vc of 25) (1-21) Mysi Farris (see problem 1-19) believes that there is a high probability that 120 pool cues can be sold if the selling price

❶ A quality control engineer is in charge of testing whether or not 95% of the Blu-ray disc players produced by his company conform to specifications. To do this‚ the engineer randomly selects a batch of 13 Blu-ray players from each day’s production. The day’s production is acceptable provided no more than 1 Blu-ray player fails to meet specifications. Otherwise‚ the entire day’s production has to be tested. (a) What is the probability that the engineer incorrectly passes a day’s production
