Sue has $8000 worth of gold in a bag. Pedro has $13,000 worth of gold in a bag. Joe, Pedro and Sue want to cross a river with their bags of gold. The only way to cross the river is to use a row boat that only has 2 seats. The row boat can handle either 2 people or one person and one bag of gold. Joe, Sue and Pedro do not trust each other. At no point can anybody be left in the presence of more gold than they own. How can Joe, Pedro and Sue cross the river? Develop a plan to move all three people across the river with their bags of gold and write your **algorithm**. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://www.pythonclassroom.com/python-curriculum-map/pedagogy/activities/river-crossing/money.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
