Question

Eduardo teaches martial arts. He charges a one−time processing fee of $10.00 and the cost of each class is shown below. Let x represent the number of classes and y represent the cost of classes. Based on this information, what will it cost, in dollars, to take 8 classes? (Do not put a $ in your answer.)

Answer 1

Start writing what you know and make an equation.
So:
Total cost = classes + processing fee

Try plugging in what the question gives you into that equation I made. What do you get?
