Maddie took a rock-climbing course at Boulder Bend Rock Gym. In addition to the fee for the 8 classes she took, the rock gym charged her $65 for climbing gear that she gets to keep. Maddie paid a total of $137. How much does each class cost?

Answer 1

Let X be the cost of each class.
Maddie paid $65 + X * 8 = $137.
Thus, Maddie took $137 - $65 = $<<137-65=72>>72 on classes.
Then, each class costs $72 / 8 = $<<72/8=9>>9. Answer: \boxed{9}.
