ABC Investments manages portfolios for a number of wealthy clients. They consider three investment types for their clients: a growth stock fund, an income fund, and a money market fund. For diversification purposes, they impose the following minimum and maximum percentages for each type of investment in each portfolio: Investment Type Minimum % Maximum % Growth Stock Fund 20% 40% Income Fund 20% 50% Money Market Fund 30% 60% The risk index and the annual yield forecast for each type of investment are as follows: Investment Type Risk Index Annual Yield Growth Stock Fund 0.1 18.0% Income Fund 0.07 12.5% Money Market Fund 0.01 7.5% Drexel has a new client with $800,000 to invest, and he would like the weighted average risk index of his portfolio to be no more than 0.05. Help Drexel come up with an investment plan that maximizes the expected annual yield of this client's portfolio.
