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
Explanation:
Step1: Subtract gear - cost from total.
Let $x$ be the total cost of 8 classes. We know that the total amount paid is $137$ and the cost of gear is $65$. So, $x=137 - 65$. $x = 72$
Step2: Calculate cost per class.
If 8 classes cost $72$, and we want to find the cost per class $y$. We use the formula $y=\frac{x}{8}$. $y=\frac{72}{8}=9$
Answer:
$9$
