ANSWER

f(x) = 2.50x + 22

EXPLANATION

Each game costs $2.50, so the cost for x games is 2.50x. To this, we have to add the initial cost of the unlimited ride pass, $22. The function is f(x) = 2.50x + 22.

The domain of this function is given by what x represents. In this case, x represents the number of games you play at the fair so it cannot be negative - note that you can't play -5 games. Hence, the domain is x ≥ 0, if x is an integer
