Maybe something like:
200s + 105a + 200 = 1,000
You can use x and y instead of s for student and a for adult.
Are the adults and students charged the same? If so then:
200x + 105x + 200 = 1,000
Negative 1 because 3 x 3 is 9 and -2 x 5 is -10. Therefore 9-10= negative 1
Your answer should be 3x-x+2=4 hope this helps..
