The expression given is \( 2.5x + 10 \), where \( 10 \) represents the fixed entry fee for the car, while \( 2.5x \) represents the total individual entry fees for both Julio and Ashley, assuming \( x \) represents the number of people (in this case, 2).
Based on this analysis, the correct interpretation of the parts of the algebraic expression would be:
- The entry fee for the car was $10.00
So, the correct answer choice is: The entry fee for the car was $10.00.
