Answer:
The number of children attended the fair is 1520.
Step-by-step explanation:
We are given the following in the question:
Entry fee foe children = $1.50
Entry fee foe adult = $4.00
Total number of people in fair = 2200
Total money collected = $5000
Let x be the number of children and y be the number of adults in the fair.
Then, we can write the following equations:
[tex]x + y = 2200\\1.5x + 4y = 5000[/tex]
Solving the two equations, we have:
[tex]1.5x + 1.5y = 3300\\1.5x + 4y = 5000\\\Rightarrow 2.5y = 1700\\y = 680\\x = 2200-680 = 1520[/tex]
Thus, there were 1520 children and 680 adults in the fair.
