This challenge is offered by Dr. Meinolf Sellmann. A freelance webpage developer received a task. A client has a budget of $10,000 and wants a webpage developed with as many features as possible while maximizing the total value of these features. The client leaves the decision of which features to the developer. She wants to delight the client and asks you which features would be best to select. We have the budget constraint and two objectives. Can you devise a rational way to trade them against each other? Link
