Eric is an option writer. in anticipation of a depreciation of the british pound from its current level of $1.50 to $1.45, he has written a call option with an exercise price of $1.51 and a premium of $.02. if the spot rate at the option's maturity turns out to be $1.54, what is eric's profit or loss per unit (assuming the buyer of the option acts rationally)?

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.
