Answer:

12

Explanation:

Number of students in Bobby's class = 30

40% of the students have blue eyes.

It means 40 out of 100 students will have blue eyes.

Then we have to find how many out of 30 students will have blue eyes.

Let us take the number of blue-eyed students out of 30 to be x.

Then:

$(40)/(100)=(x)/(30)\\x=(40)/(100)*30\\x=12$ .

Hence 12 out of 30 students will have blue eyes.
