Exhibit 3.4 The following questions are based on this problem and accompanying Excel windows. A financial planner wants to design a portfolio of investments for a client. The client has $300,000 to invest, and the planner has identified four investment options for the money. The following requirements have been placed on the planner. No more than 25% of the money should be invested in any one investment, at least one third should be invested in long-term bonds that mature in seven or more years, and no more than 25% of the total money should be invested in C or D since they are riskier investments. The planner has developed the following LP model based on the data in this table and the requirements of the client. The objective is to maximize the total return of the portfolio.
