Problem 566409: Do not include anything other than numbers in your responses. For example, do not include comma or dollar sign in your numbers. As a rule of thumb, keep 2 decimal places for larger numbers and 3 decimal places for smaller numbers less than 1. Joe's Slop House is a little hole in the wall restaurant that serves slowcooked barbecue beef sandwiches. The beef for the sandwiches cooks overnight, so each evening Joe decides how much beef to cook for the next day. The beef costs $2.5 a pound and Joe sells each sandwich (filled with 1 pound of beef) for $5.5. At the end of the day, any leftover beef is given to the neighborhood church for their soup kitchen. The tax deduction for this is worth $0.5 a pound. Daily demand for the beef can be approximated by a normal distribution with a mean of 230 pounds and a standard deviation of 35 pounds. Cost of Shortage (Cs): Cost of Excess (Ce): What is the optimal service level? What is the corresponding z value? How many pounds of beef should Joe cook for the next day
