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.)

=125,000
