nia has $19.50 to ride the subway around new york. it will cost her $0.75 every time she rides. identify the dependent variable and independent variable in this scenario.
a the number of rides and the total cost are both independent variables.
b the number of rides and the total cost are both dependent variables.
c the number of rides is the independent variable, and the total cost is the dependent variable.
d the total cost is the independent variable, and the number of rides is the dependent variable.

Explanation:

An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. Here, the number of subway - rides can be chosen freely (Nia can choose how many times to ride), and the total cost depends on the number of rides (total cost = 0.75×number of rides). So the number of rides is the independent variable and the total cost is the dependent variable.

Answer:

C. The number of rides is the independent variable, and the total cost is the dependent variable.
