When traveling in two schools, A: 100 or more, and B: 100 or less. The two schools need 20,800 yuan for a separate group, and only18,000 yuan for a joint group.

@ "Science and Family Education" answers for you.

(1) because 85 * 200 =17000 <18000.

Therefore, the total enrollment of the two schools exceeds 200.

(2) Solution: There are X students studying in a school and Y students studying in a school, and the equation is listed according to the meaning of the question.

{85x+90y=20800

75(x+y)= 18000

Solve the equation:

{x= 160

y=80

A: (1) The total number of students enrolled in the two schools exceeds 200;

(2) A school enrolls 160 students, and a school enrolls 80 students.
