On Saturday, $585 was collected from the sale of 55 tickets for a performance. The cost of an adult ticket was $12 and the cost of a student ticket was $9. Find the number of adult tickets
and the number of student tickets sold on that day.
I

12(.25)= 3. 12-3= 9 for student tickets

x = adult tickets

y = student tickets

x + y = 55

12x + 9y= 585

-12x - 12y = -660

-3y = -75

3y = 75

y = 25 student tickets

x + 25 = 55

x = 30 adult tickets
