#7) f(x) = %3D # 8) Rosewood Clothing manufactures hockey jerseys for sale to college bookstores. Its cost (in dollars) for a run of x jerseys is C(x) = 2000 + 10x + 0.2x2. How many jerseys should Rosewood produce per run to minimize average cost? What is the average cost? # 9) Suppose a flu epidemic hits a city in such a way that the healthy population seems to be following the function P(t) = 100,000 – 60t2 + t3, where t is the number of days after the onset of the epidemic. (a) For what time t is the population decreasing? (b) When will the population be a minimum? (c) What will this population be?
