Answer:
The correct answer is:
The number of rides is the independent variable, and the total cost is the dependent variable.
An **independent variable** is a variable that can be changed or manipulated by the experimenter or the situation, while a **dependent variable** is a variable that depends on or responds to the independent variable.
In this scenario, Jewels can choose how many times she rides the ferry, so the number of rides is the independent variable. The total cost of riding the ferry depends on how many times she rides, so the total cost is the dependent variable. We can write an equation to relate these two variables:
total cost = 0.45 * number of rides
This equation shows that for every ride, the total cost increases by 0.45 dollars. The total cost also depends on the initial amount of money that Jewels has, which is 6.75 dollars. We can subtract this amount from both sides of the equation to get:
total cost - 6.75 = 0.45 * number of rides - 6.75
This equation shows that as the number of rides increases, the difference between the total cost and 6.75 dollars also increases. This difference represents how much money Jewels has left after riding the ferry. If she wants to have some money left, she cannot ride more than 15 times, because then the difference would be negative.
