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.

Scientists developed the first successful human cell culture in vitro (grown in a lab) in the 1950s by removing cancer cells from a woman. this concept has allowed modern scientists to successfully grow organs. which of the following answers  bestdetermines why there was success?   neurons send a signal to the cell to multiply.a large blood supply to the cell allows enough nutrients for growth.cells are the basic unit of life and thus can regenerate if in a controlled environment.cells cannot reproduce on their own, and the scientist manipulates them to grow.
