Ok so basically, the number of student tickets is 3x, where x=the number of adult tickets sold. And we know that s(for student tickets)+x=480 total tickets sold. So if we replace s with 3x we have 3x+x=480, or 4x=480. We divide by 4 and get x=120, which is the amount of adult tickets sold.
Use the form to you know yeah
c

(
b
x
-

)

to find the variables used to find the amplitude, period, phase shift, and vertical shift.
