    Answer: B

    Step-by-step explanation:

    The total cost is dependent because it relies on how many rides Nia takes, and the $19.50 limit.

    The number of rides is dependent on the limit of $19.50 because the $19.50 is the limit and the total amount of rides is locked by $19.50

    I'm not sure, though.

    The correct answer is B. The number of rides and the total cost are both dependent variables, as both depend on the amount of money that Nia has.

    Step-by-step explanation:

    Both the number of rides and the total cost are variables that depend on the amount of money that Nia has. This is so because the passage has a cost, and that cost can not exceed the amount of money that Nia has, because if she exceeds her $ 19.50 she won't be able to pay the ticket. Then, Nia has a possible amount of 26 rides as maximum (19.5 / 0.75 = 26), and the maximum total cost that can be paid is $ 19.50.
