To interpret the expression \(2.5x + 10\), we need to identify the parts of the expression.
- The term \(2.5x\) suggests that each individual entry fee is $2.50, where \(x\) represents the number of people (in this case, two people: Julio and Ashley).
- The constant term \(10\) represents the fixed entry fee for the car.
Given this breakdown, we can conclude:
- Each individual entry fee was $2.50.
- The entry fee for the car was $10.00.
From the provided choices, the correct interpretation of a part of the algebraic expression is:
Each individual entry fee was $2.50.
Also, the entry fee for the car was $10.00. Thus, the correct responses are consistent with this interpretation.
