8 students because if you subtract 600 from 200 you get 400 and if you divide 400 by 50 you get 8

Answer: D) 8 students


Explanation:

Since $200 is already covered, you would subtract 200 from the total cost to find out how much you need left.

600-200-400

Next, you do 400/50 because each student would cover $50.

400/50=8

Therefore, your answer is 8 students.
