kalila purchases 4 tickets, 3 of which are youth tickets.
kalila purchases 4 tickets, 3 of which are adult tickets.
kalila purchases 4 adult tickets and 3 youth tickets.
kalila purchases 4 youth tickets and 3 adult tickets.

Kalila purchases 4 adult tickets and 3 youth tickets.

Step-by-step explanation:

Let x represents the number of adults ticket and y represents the number of youth tickets that Kalila bought,

Since, the cost of one adult ticket = $ 18

⇒ The cost of x adult tickets = 18 x

Also, the cost of one youth ticket = $ 12

⇒ The cost of y youth tickets = 12 y

Thus, the total budget of Kalila = 18 x + 12 y

But, her budget can not exceeded to $ 250

⇒ 18 x + 12 y ≤ 250

Which is the inequality that shows the number of tickets she can buy,

If, The ordered pair (4, 3) is a solution of the above inequality.

Then we can write x = 4 and y = 3

⇒ Kalila purchases 4 adult tickets and 3 youth tickets.
