M. cotteleer electronics supplies microcomputer circuitry to a company that incorporates microprocessors into refrigerators and other home appliances. one of the components has an annual demand of 235 units, and this is constant throughout the year. carrying cost is estimated to be $1.25 per unit per year, and the ordering (setup) cost is $21 per order. a) to minimize cost, how many units should be ordered each time an order is placed? b) how many orders per year are needed with the optimal policy? c) what is the average inventory if costs are minimized? d) suppose that the ordering cost is not $21, and cotteleer has been ordering 125 units each time an order is placed. for this order policy (of q = 125) to be optimal, determine what the ordering cost would have to be.

Aproduct has a demand of 4000 units per year. ordering cost is $20, and holding cost is $4 per unit per year. the cost-minimizing solution for this product is to order: ? a. 200 units per order. b. all 4000 units at one time. c. every 20 days. d. 10 times per year. e. none of the above

In a fixed-term, level-payment reverse mortgage, sometimes called a reverse annuity mortgage, or ram, a lender agrees to pay the homeowner a monthly payment, or annuity, and expects to be repaid from the homeowner’s equity when he or she sells the home or obtains other financing to pay off the ram. consider a household that owns a $150,000 home free and clear of mortgage debt. the ram lender agrees to a $100,000 ram for 10 years at 6 percent. assume payments are made annually, at the beginning of each year to the homeowner. calculate the annual payment on the ram.
