Answer:
Red= 0.18
Blue= 0.32
Step-by-step explanation:
0.2+0.18+0.12=0.50.
So the info we have is half of the circle. And the info we don't have is the other half of the circle. So we break the info apart.
Yellow and green added together equal the same size as blue:
--> 0.32
And white is the same size as red:
--> 0.18
Let x as number of adult tickets and y as number of student tickets
x+y=1260
y=1260-x
5x+1y=2688
5x+1(1260-x)=2688
5x+1260-x=2688
4x=2688-1260
x=1428÷4
x=357 adult tickets sold
y=1260-357
y=903 student tickets sold
