Let's say you have the equation
5x + 3y = 11
You are asked to test the ordered pair (1, 2) to see if it is a solution of the equation. A solution of the equation will make the equation a true statement. The ordered pair (1, 2) has 1 as its x-coordinate and 2 as its y-coordinate.
Substitute 1 for x and 2 for y in the equation. Then work it out to see if it is a true statement.
5x + 3y = 11
5(1) + 3(2) = 11
5 + 6 = 11
11 = 11
Since 11 = 11 is a true statement, the ordered pair (1, 3) is a solution of the equation.

Answer:
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:
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.
4*2/7=8/7 and 8/7*5=40/7 so correct answer is 40/7
