Linear Systems

Company A:




An electronic retail chain wishes to minimize its ordering costs for a particularly popular model
of laptop computer.  This retail chain has a line of credit to finance its inventory and the current
holding rate is 5.5%.  The chain estimates it can sell 670,000 units per year and it pays $375 dollars
per unit.  It costs $32 dollars to place each order.  How many units should it order each time?
You should round your answer up to the nearest laptop unit.







Company B:




A manufacturer of laptop computers operates a plant with an annual capacity of 148,070,000
laptop units.  One of its models is expected to sell 8,710,000 units in the coming year. 
How large should each product lot be if it costs $375 to change production from one model to
another.  Assume that the manufacturer values each laptop unit at $190 dollars and it has a
holding rate of 6.5%.  You should round your answer up to the nearest laptop unit.
