A company knows that they will sell 80,000 cases of #2 Pencils
at a steady rate over the course of the next year. It costs them
$12 a year to warehouse each case, based on the average number of
cases in the warehouse, and it costs them $100 each time a delivery
is made to their warehouse. How many orders should they place each
year in order to minimize their total inventory costs? Assume that
the orders are all of equal size. Round your answer to the nearest
whole number.
