1c. LZ Girl makes recliners. One plant assembles the L-4000 model. Standards indicate that one worker can assemble five recliners per day. The company estimates it costs $9 to hold one recliner in inventory for one month. Workers earn $2000 per month and can be hired for $1500 each. Laying off a worker costs $3000. Currently, there are 14 workers in the assembly department. No backorders are allowed. The inventory on hand at the end of June was 400 units. Assume that you want to have at least 300 units in inventory at the end of December, you must hire and layoff in integer numbers of workers, and that you must always produce at capacity. Note: You should add the cost of the 300 units of inventory added to net demand in the last month to properly account for inventory costs.
