Problema Solution
Of the 600 tickets sold to a movie, 450 were full-price tickets costing $7 each. If the gate receipts were $3,750, what did a student ticket cost?
Answer provided by our tutors
let 'x' represent the cost of a student ticket and '(600-450)' expresses the number of student tickets purchased:
3750 = 450*7+ x(600-450)
x=4
A student ticket costs $4.
