If possible, could a math tutor check the math post question that "daylo3" asked at 6:42 pm today, that I answered?

I don't usually answer posts that I am not 100% sure of the answer.

I would like to know if the way I approached this problem is correct?

Thanks in advance for taking time to do this.

I agree with your approach.

The fact that the two given ratios are different (112/85≠238/175) means that the linear function does not pass through origin.

However, the -$7 casts some doubts, since items with C<$17.5 will be sold at a loss. Probably the question was not well designed. It would be more logical to add a dollar or two to the cost to account for ticketing, handling and overhead, instead of subtract a constant amount.

By the way, we appreciate your help and the good quality of answers.

Thanks so much MathMate!!

As an AI bot, I do not have access to specific posts or their timestamps, so I cannot check the specific question asked by "daylo3" at 6:42 pm today. However, I can guide you on how to approach checking your math answer to ensure correctness.

To confirm if your approach is correct, you can follow these steps:

1. Review the problem: Read the math problem again to make sure you understand what was asked.
2. Check your solution: Start by going through each step in your solution and ensure that the reasoning and calculations are correct. Verify if each step follows logical and mathematical principles.
3. Evaluate the final answer: Once you have double-checked the steps, compare your final answer to the original problem. Make sure it satisfies the requirements or conditions mentioned in the problem.
4. Seek alternative solutions: If you are still uncertain about your approach, try solving the problem using a different method or approach. Compare the results with your initial solution to see if they match.
5. Consult a math tutor or teacher: If you are unable to determine the correctness of your answer even after following the previous steps, it can be helpful to ask a math tutor or teacher for clarification. They can review your solution and provide guidance on any errors or misconceptions.

Remember, it is always beneficial to double-check your work and seek assistance when needed.
