Neilsen Cookie Company sells its assorted butter cookies in containers that have a net content of 1 lb. The estimated demand for the cookies is 500,000 1 lb containers. The setup cost for each production run is $507, and the manufacturing cost is $0.53 for each container of cookies. The cost of storing each container of cookies over the year is $0.36. Assuming uniformity of demand throughout the year and instantaneous production, how many containers of cookies should Neilsen produce per production run in order to minimize the production cost? Hint: Following the method of Example 5, show that the total production cost is given by the function below. Then minimize the function C on the interval (0, 500,000). (Round your answer to the nearest whole number.) C(x) = 253,500,000 x + 0.18x + 265,000.

In establishing warranties on HDTV sets, the manufacturer wants to set the limits so that few will need repair at the manufacturer's expense. On the other hand, the warranty period must be long enough to make the purchase attractive to the buyer. For a new HDTV the mean number of months until repairs are needed is 36.84 with a standard deviation of 3.34 months. Where should the warranty limits be set so that only 10 percent of the HDTVs need repairs at the manufacturer's expense? (Round z-score computation to 2 decimal places. Round your final answers to 2 decimal places.)

g is constructing a triangular sail for a sailboat. Aluminum supports will run along the horizontal base and vertical height of the sail, respectively. After making some measurements, Calculo determines that the height of the sail cannot exceed 12 feet, or else it will not be able to fit under the bridges in the area. In addition, the total weight of the supports cannot exceed 80 pounds, or else the boat will sink. If aluminum weighs 5 pounds per foot, what is the area of the largest sail Calculo can build? Fully justify your answer, doing each step you learned in the class prep. In particular, you must show that the area you found is indeed the largest possible.

Before the last school year began, it was estimated that the average discretionary personal expenses each school year for a student attending a 4-year public college were $2,110. This past summer Ashley decided to poll seven of her friends attending a 4-year public college because she thought that estimate was low. She made a list of their actual school-year expenses: $2,800, $1,990, $2,005, $2,400, $1,860, $2,200, $2,000 What is the mean of her friends' personal expenses? Round your answer to the nearest cent. Is the average higher or lower than the estimate? What would Ashley's actual personal expenses for that school year have to be so that her amount and her friends' amounts together would have an average of $2,110?
