### Exam Score Analysis for Fifth-Grade Students

Students in a fifth-grade class were given an exam. During the next 2 years, the same students were retested several times. The average score was given by the function

\[ f(t) = 89 - 14 \log(t + 1), \quad 0 \leq t \leq 24 \]

where \( t \) is the time in months.

#### Questions:

**(a) What is the average score on the original exam the students took?**  
*Answer Here:*

**(b) What was the average score after 6 months?**  
*Answer Here:*

**(c) What was the average score after 18 months?**

Explanation:

1. **Function Description**:
    - The function \( f(t) = 89 - 14 \log(t + 1) \) models the average score of the students over time.
    - Here, \( t \) represents the number of months since the original exam.

2. **Constraints**:
    - \( 0 \leq t \leq 24 \): This means that the function is valid for the time period from 0 to 24 months (0 months being the time of the original exam, and 24 months being 2 years later).

#### Graphs and Diagrams
There are no graphical representations or diagrams provided in the image. The analysis is solely based on the mathematical function provided.
