14. The school organized a visit to the Expo Park for all third-grade students, renting some large buses. The teacher originally planned for 28 students per bus, but after everyone boarded, it was found that 13 students could not get on. So, it was decided that each bus would carry 32 students, and as a result, there were 3 empty seats on the bus. How many third-grade students are there in the school? How many large buses were rented?
【Solution】Solution: Let $x$ be the number of large buses rented,
$$
\begin{aligned}
28 x+13 & =32 x-3 \\
4 x & =16 \\
x & =4 \\
28 \times 4+13 & =125 \text { (people) }
\end{aligned}
$$

Answer: The school has a total of 125 third-grade students, and 4 large buses were rented.
