To find the price per golf ball, divide the total cost of the golf balls by the number of golf balls purchased.
\[ \text{Price per golf ball} = \frac{\text{Total cost}}{\text{Number of golf balls}} = \frac{10.08}{24} \]
Calculating this:
\[ \frac{10.08}{24} = 0.42 \]
Therefore, the price per golf ball is $0.42.
