Formulate but do not solve the problem. Mr. and Mrs. Garcia have a total of $125,000 to be invested in stocks, bonds, and a money market account. The stocks have a rate of return of 12%/year, while the bonds and the money market account pay 7%/year and 3%/year, respectively. The Garcias have stipulated that the amount invested in the money market account should be equal to the sum of 15% of the amount invested in stocks and 20% of the amount invested in bonds. How should the Garcias allocate their resources if they require an annual income of $11,000 from their investments? (Let x, y, and z denote the amount, in dollars, in stocks, bonds, and money markets, respectively.)
