14. Teacher Li went to the toy store to buy balls. The money he brought was just enough to buy 60 plastic balls. If he didn't buy plastic balls, he could buy 36 glass balls or 45 wooden balls. Teacher Li finally decided to buy 10 plastic balls and 10 glass balls, and use the remaining money to buy wooden balls. How many balls did Teacher Li buy in total?
【Analysis】Assuming there is 1 portion of money, then the prices are as follows:
\begin{tabular}{|c|c|c|c|}
\hline Ball & Plastic Ball & Glass Ball & Wooden Ball \\
\hline Price & $\frac{1}{60}$ & $\frac{1}{36}$ & $\frac{1}{45}$ \\
\hline
\end{tabular}
$\left(\frac{1}{60}+\frac{1}{36}\right) \times 10=\frac{3+5}{180} \times 10=\frac{4}{9}$
$\left(1-\frac{4}{9}\right) \div \frac{1}{45}=25($ pieces $)$ ... Wooden Balls
Total $10+10+25=45$ (pieces)
