Answer:

Step-by-step explanation:

Let "a" represent the number of adult tickets sold. Then the total revenue is ...

5a +3(200-a) = 720

2a +600 = 720 . . . . . . simplify

2a = 120 . . . . . . . . . . . . subtract 600

a = 60 . . . . . . . . number of adult tickets sold

200-a = 140 . . . number of tickets for children sold
