I think that the answer is 3Y+30. I hope this helps!!! :)
What table ? Kinda confusing
213+497=710 total students, so 213 wore a silly hat so that would be 30% wore the silly hats
4x + 6 = -26
I'm not sure if your supposed to solve, but I will anyways :)
4x + 6 = -26
-6 -6
4x = -32
x = -8
Hope this helps!
The equation of the blue graph is A.
