The algebraic expression given is \(2.5x + 10\), where \(x\) represents the number of individual entry fees for Julio and Ashley.
- The term \(10\) in the expression represents the fixed fee for the car.
- The term \(2.5x\) represents the individual entry fees for both Julio and Ashley.
If \(x\) is the number of individual entry fees and each fee is \(2.5\), then it implies that each individual entry fee is \(2.5\), not \(10\) or \(12.5\).
Therefore, the correct interpretation of the parts is:
- The entry fee for the car was $10.00.
- Each individual entry fee was $2.50.
However, from the options you provided, it appears we need to choose the option that fits what the question is asking.
So the correct answer would be: Each individual entry fee was $2.50.
