Answer: If I were you, I would guess 320 students.
Step-by-step explanation:
1.) Think about it, 400 students were asked the same question and 80 chose to fight for lemonade on the school menu. 4/5 or 320 students put Guess.
2.) It's true that 400 students voted, but 80 voted yes, and 320 voted guess.
3.) Further Explanation:
1/5 times 400 equals 80. It's true only 80 students voted yes. 4/5 times 400 equals 320 students voted guess.
