Question 1016543
 Of the 700 tickets sold to a movie, 480 were full-price tickets costing $9 each.
 If the gate receipts were $5,200, what did a student ticket cost?
:
Find the number of student tickets
700 - 480 = 220 
:
let s = the cost of the student tickets
:
220s + 480(9) = 5200
220s + 4320 = 5200
220s = 5200 - 4320
220s = 880
s = 880/220
s = $4 for the student tickets
