Answer:
5
Explanation:
To find out how many golf balls Rafael used at the driving range, we can use the following formula:
number of balls used at the driving range = total number of balls x percentage used
Given:
Total number of balls = 25
Percentage used = 20%
So we can substitute these values into the formula:
number of balls used at the driving range = 25 x 20% = 25 x 0.20 = 5
Therefore, Rafael used 5 golf balls at the driving range.
