Answer:

Step-by-step explanation:

Let x represent the number of youth tickets purchased at the zoo.

Let y represent the number of adult tickets purchased at the zoo.

At the zoo, youth tickets cost $5 and adult tickets cost $9. A group spent a total of $90 on tickets. This means that

5x + 9y = 90

The domain of the relationship is the possible set of values of x and y that satisfies the equation. The domain of this relationship is

0 ≤ x ≤ 18

At x = 0, it means only adult tickets were purchased.

At x = 18, it means only youth tickets were purchased.
