Final answer:
To find the number of boys on the swim team, subtract the percentage of girls from 100%.
Step-by-step explanation:
To find the number of boys on the swim team, we first need to calculate the total number of students on the team. We know that there are 12 girls on the team, which make up 48% of the students. Since 48% is less than half, the number of boys must be greater. Using this information, we can set up the equation:
12 + x = 100%
Where x represents the percentage of boys on the team. We can solve for x by subtracting 48% (the percentage of girls) from 100%:
x = 100% - 48%
x = 52%
Therefore, 52 boys make up the remaining percentage on the team, so the answer is D.
