Answer:

The adult tickets are 400 and the children tickets are 300.

Step-by-step explanation:

Given:

At a carnival, 700 tickets were sold for a total  amount of $5500. An adult ticket cost $10   and a children's ticket cost $5.

Now, to find the  number of adult tickets and the number of  children's tickets sold.

Let the number of adult tickets be [tex]x.[/tex]

And let the number of children tickets be [tex]y.[/tex]

So, the total number of tickets sold:

[tex]x+y=700\\\\y=700-x\ \ \ ....(1)[/tex]

Now, the total amount of tickets:

[tex]x(10)+y(5)=5500[/tex]

Substituting the value of [tex]y[/tex] from equation (1):

[tex]x(10)+(700-x)(5)=5500\\\\10x+3500-5x=5500\\\\5x+3500=5500[/tex]

Subtracting both sides by 3500 we get:

[tex]5x=2000[/tex]

Dividing boths sides by 5 we get:

[tex]x=400.[/tex]

The number of adult tickets = 400.

Now, substituting the value of [tex]x[/tex] in equation (1) we get:

[tex]y=700-x\\\\y=700-400\\\\y=300.[/tex]

The number of children tickets = 300.

Therefore, the adult tickets are 400 and the children tickets are 300.
