Tickets

Tickets to the zoo cost $4 for children, $5 for teenagers and $6 for adults. In the high season, 1200 people come to the zoo every day. On a certain day, the total revenue at the zoo was $5300. For every 3 teenagers, 8 children went to the zoo. How many teenagers, children, and adults went to the zoo?

Result

a =  100
c =  800
t =  300

Solution:


6a + 5t + 4c = 5300
a + t + c = 1200
(8/3)*t = c

6a+4c+5t = 5300
a+c+t = 1200
3c-8t = 0

a = 100
c = 800
t = 300
