The answer is y=20 because if they’re proportional then they increase at the same rate. to get from c=3 to x=15 u multiply by 5 and dice x and y are proportional you would multiply the y value, y=4 by 5 to get y=20

Answer:
350 students
Step-by-step explanation:
Let:
a = number of adults attending
s = number of students attending
a + s = 950 (1) (given)
9a + 6.5s = 7675 (2) (cost per adult * number of adults + cost per student * number of students = total amount spent)
Looking for s. Multiply (1) by 9 then subtract eq (2), this will eliminate the variable a:
(1) 9a + 9s = 8550
- (2) 9a + 6.5s = 7675
-------------------------------
0a + 2.5s = 875
s = 875/2.5 = 350 students
