Its high cost and perishability forced the National Health Service to have small amount of stocks, used to satisfy demand of not more than three days.
Plan the supply of the drug of the National Health Service taking into account the number of packages of the drug distributed in the last 20 days (see given Table).
Table: Number of packages (three vials each) of Neurozan distributed over the last 20 days from the Belgian
