Blair \& Rosen, Inc. (B\&R) is a brokerage firm that specializes in investment portfolios designed to meet the specific risk tolerances of its clients. A client who contacted B8R this past week has a maximum of $50,000 to invest. B8R's investment advisor decides to recommend a portfolio. consisting of two investment funds: an Internet fund and a Blue Chip fund. The Internet fund has a projected annual return of 18%, and the Blue Chip fund has a projected annual return of 8%. The investment advisor requires that at most $25,000 of the client's funds should be invested in the internet furd. Bs. services include a risk rating for each investment aiternative. The internet fund, which is the more risky of the two investment alternatives, has a risk rating of 5 per thousand dollars invested. The Blue Chip fund has a risk rating of 5 per thousand dollars invested. For example, if $10,000 is invested in each of the two investment funds, BaR's risk rating for the portfolio would be 5 (10) + S(10)=100. Finally, B8R developed a questionnaire to measure each client's risk tolerance, Based on the responses, each client is classified as a conservative, moderate, or aggressive investor. Suppose that the questionnaire results classified the current client as a moderate investor. BQR recommends that a client who is a moderate investor limit his or her portfolio to a maximum risk rating of 230. (a) Formulate a linear programming model to find the best investment strategy for this client. Let I= Internet fund investment in thousands B= Blue Chip fund investment in thousands If required, round your answers to two decimal places. If an amount is zero, enter " 0 ". If the constant is " 1 " it must be entered in the box. (b) Bulld a spreadsheet model and solve the problem using Solver. What is the recommended investment portfolio for this client?
