To solve the situation described, we need to account for the membership fee and the cost per hour of using the court. The total cost consists of the $50 membership fee and the $15 per hour charge for playing tennis.
The equation to represent this situation is:
\[ 50 + 15h = 100 \]
Where:
- \(50\) is the membership fee,
- \(15h\) is the total cost for \(h\) hours of court use,
- \(100\) is the total amount of money you have to spend.
This equation correctly reflects the relationship and can be used to solve for \(h\). Therefore, the correct response is:
50 + 15h = 100
