.
I am not going to ask questions.
I am going to make a statement.
I just answered to your post yesterday in
https://www.algebra.com/algebra/homework/word/misc/Miscellaneous_Word_Problems.faq.question.1072768.html
https://www.algebra.com/algebra/homework/word/misc/Miscellaneous_Word_Problems.faq.question.1072768.html
that  (I am repeating)
    There is NO enough info to answer the question.
    Indeed, we have ZERO information regarding C.
    It is strange from your side to submit such a nonsense.
I state that this my answer is correct.
With all consequences that follow from this statement.
I hope other tutors will/can confirm that I was right then and I am right now.
What I do not understand is this: did you read my answer and do you understand the meaning of my words .
Sorry.

Comment from student: i did. and that is the question. if you see this question again, please don't respond, so i can clarify with other tutors.

My response:   OK, I got it.
                       I will be silent next time.
