The expression \( 2.5x + 10 \) represents the total cost, where \( x \) stands for the number of people (Julio and Ashley in this case) and the fees are broken down as follows:
- \( 2.5x \) indicates that each individual entry fee is $2.50.
- The \( +10 \) indicates a flat fee, which would represent the entry fee for the car.
From this breakdown, we can interpret that:
- The entry fee for the car was $10.00 (the constant term in the expression).
- Each individual entry fee was $2.50 (the coefficient of \( x \)).
Thus, the correct interpretation from the choices would be:
The entry fee for the car was $10.00.
