400 children and 600 adults bought tickets.
Step-by-step explanation:
Given,
Cost of one child ticket = $14
Cost of one adult ticket = $32
Total attendance = 1000
Revenue generated = $24800
Let,
x be the number of children.
y be the number of adults.
According to given statement;
x+y=1000 Eqn 1
14x+32y=24800 Eqn 2
Multiplying Eqn 1 by 14

Subtracting Eqn 3 from Eqn 2

Dividing both sides by 18

Putting y=800 in Eqn 1

400 children and 600 adults bought tickets.

Subtract 6.7 from 20. This is 13.3. Divide 13.3/5 is 2.66. That is the answer
I think if you take 360 and divide it by 55 thats how many busses they used. Then take that answer and divide it by 13 to find how many vans were used.
