C Correct answer
Explanation

36% eat breakfast, so 64% do not. In a class of 25, 0.64 * 25 = 16 students do not eat breakfast. Total classes = 2200. Total students not eating = 2200 * 16 = 35,200.

AI explanation

Using the method of proportions, the total number of students in the state is 25 multiplied by 2200, which equals 55000. Since 36 percent eat breakfast daily, 64 percent do not. We calculate 64 percent of 55000, which is 0.64 times 55000, resulting in 35200 students who do not eat breakfast every day.
