A gas station sells Q gallons of gasoline per year, which is delivered N times per year in equal shipments of gallons. The cost of each delivery is d dollars and the yearly storage costs are sQT, where T is the length of time (a fraction of a year) between shipments and s is a constant. Which value of N minimize the costs? Hint: Express T in terms of N. (Use symbolic notation and fractions where needed.) N = Find the optimal number of deliveries if Q = 5 million gal, d = $7000, and s = 29 cents/gal-yr. (Your answer should be a whole number, so compare costs for the two integer values of N nearest the optimal value.) N = |
