At a carnival, 700 tickets were sold for a total
Diano4ka-milaya [45]

Answer:

The adult tickets are <u>400</u> and the children tickets are <u>300</u>.

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.

<em>Let the number of adult tickets be </em>x.<em />

<em>And let the number of children tickets be </em>y.<em />

So, the total number of tickets sold:

x+y=700\\\\y=700-x\ \ \ ....(1)

Now, the total amount of tickets:

x(10)+y(5)=5500

Substituting the value of y from equation (1):

x(10)+(700-x)(5)=5500\\\\10x+3500-5x=5500\\\\5x+3500=5500

<em>Subtracting both sides by 3500 we get:</em>

<em />5x=2000<em />

<em>Dividing boths sides by 5 we get:</em>

x=400.<u />

<u>The number of adult tickets = 400.</u>

Now, substituting the value of x in equation (1) we get:

y=700-x\\\\y=700-400\\\\y=300.

<u>The number of children tickets = 300.</u>

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