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.

**MathMate**, Saturday, January 29, 2011 at 9:57pmI 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.
