Excited to buy her dream car, Molly rushes into her local Jeep dealership. Molly picks out a car, sits down at the financing desk, and hears the following:"Well, we ran your credit history. You’ve got a really thin file -- just a year’s worth of student loan payments. The deal you saw was for ‘well qualified buyers.’ The best deal we can offer you is 6.6% for 60 months. A little more bad news -- the cash allowance is also based on credit history, so you don’t qualify for $500. That said, you’re excited about a Jeep, and I want to see you driving one, so I can do $400 for you!"Molly still has a $2500 down payment. How much loan does Molly need?

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.
