Explanation
Problem Analysis The problem states that a plumbing company charges a flat fee of $60 for an emergency service call. We are asked to determine which phrase describes the number of hours the plumbing company was at the service. However, the problem does not provide any information about the relationship between the fee and the number of hours. Therefore, we cannot determine the number of hours the plumbing company was at the service.
Reasoning Since we don't have any information relating the flat fee to the number of hours, we cannot determine if the plumbing company was at the service for at most 2 hours, at least 2 hours, at most 3.5 hours, or at least 3.5 hours.
Conclusion Therefore, none of the given phrases can be determined to be correct based on the information provided.
Examples
This problem highlights the importance of having sufficient information to solve a problem. In real life, if you want to determine how long a service will take based on the cost, you need to know the rate at which the service is charged. For example, if you know the plumbing company charges $60 per hour, then you can determine the number of hours they worked based on the total cost. Understanding the relationship between different variables is crucial in solving real-world problems.
