Your broker requires an initial margin of $6,075 per wheat futures contract and a maintenance margin of $4,500 per contract. Wheat futures contracts cover 5,000 bushels and are quoted in cents per bushel. You sold one wheat futures contract yesterday at the closing settlement price quote of 786. Today, the settlement quote is 808. Will you receive a margin call and if so, for what amount? All margin calls restore the margin level to its initial level. What price per bushel will trigger a margin call?

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.
