Question
**Investment Problem**

An investor has $24,000 to invest in bonds of AAA and B qualities. The AAA bonds yield an average of 6%, and the B bonds yield 10%. The investor requires that at least three times as much money should be invested in AAA bonds as in B bonds. How much should be invested in each type of bond to maximize the return? What is the maximum return?

**Graph Explanation**

The image contains a coordinate grid that appears blank without any markings, labels, or data points. It seems to be prepared for plotting data relevant to the investment problem, such as the potential investments in AAA and B bonds, constraints, and potential returns.
