Final answer:
Without additional information regarding the roommate's utilities and negotiation outcomes, the ideal contribution to the internet bill cannot be determined.
Step-by-step explanation:
The ideal amount each roommate should contribute to the internet bill cannot be determined from the given information due to the differing preferences and financial situations of Joshua, Omar, and Brendan. To solve this issue, they must engage in negotiation or utility analysis to find a contribution that maximizes overall satisfaction, considering Joshua's tolerance range for contribution, Omar's preference for high-quality internet, and Brendan's budget constraints. A common approach might involve finding a compromise that balances the utilities of all three roommates by assigning a weight to the intensity of each roommate's preferences or some other method of utility quantification.
