Suppese a certain manufacturing compacy produces connecting rods for 4- and 6-eyinder autemobile engines using the same production line. The cost required to sat up the production line to preduce the 4-cylindergonnecting rods is 52,400 , and the cost required to set up the production line for the 6-cylinder connecting rods is 53,500 . Manufachuring costs are 512 for each 4cylinder connecting red and 51% for each 6 - Cylinder connecting rod. Hamkins makes a decision at the end of each neek as to which peoduct will be manufictured the fodlowing week. If a production changeover is necessary from one week to the cent, the metlend is used to reconfigure the production line. Once the ine has been set up, the weeldy production capacities are 5 ,ooo 6 -cylinder conneding rods and 9,0004c-hlinder connecting rods.
