Tickets to the school play cost $4.50 for adults and $3.00 for students. One night 325 tickets where sold and 1140 was collected. How many of each type was sold?
4.50x+3x=1140 You will add 4.50 and 3 together to get 7.5. your equation is now... 7.50x=1140 you divide by 7.5 and get 152. so x= 152. I am stuck now.
