What is a great system to manage money and prevent taking too much from one category? describe the
system in a way that someone who has never heard of it could understand.

The management of a private investment club has a fund of $250,000 earmarked for investment in stocks. to arrive at an acceptable overall level of risk, the stocks that management is considering have been classified into three categories: high risk (x), medium risk (y), and low risk (z). management estimates that high risk stocks will have a rate of return of 15%/year; medium risk stocks, 10%/year; and low risk stocks, 6%/year. the amount of money invested in low risk stocks is to be twice the sum of the amount invested in stocks of the other two categories. if the investment goal is to have a rate of return of 9% on the total investment, determine how much the club should invest in each type of stock. (assume that all the money available for investment is invested.)

Yael decides that she no longer enjoys her job, and she quits to open a gluten-free, dairy-free kosher bakery. she pays a monthly rent for her store of $2,000. her labor costs for one month are $4,500, and she spends $6,000 a month on nut flours, sugar, and other supplies. yael was earning $2,500 a month working as a bank teller. these are her only costs. her monthly revenue is $14,000. which of the following statements about yael’s costs and profit are correct? correct answer(s) an accountant would say she is earning a monthly profit of $1,500. her implicit costs are $2,500 a month. an economist would tell her that she is experiencing a loss. her total costs are $12,500 a month. her explicit costs include the labor, rent, and supplies for her store. her economic profit is $1,500 a month.

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.
