Question

A taxi cab charges an initial fee of $4 and an additional fare of $0.25 per mile of travel. In the function that represents this example, if the dependent variable is

the cost of the cab fare, what would be the independent variable?

Answer 1

The independent variable is the initial fee of $4

Explanation:

Initial fee of $4

Additional fare of $0.25 per mile

Answer 2

amount of miles traveled

Explanation:

The dependent variables depends on another variable.

What that variable depends on is called the independent variable.

So the cost of the cab fare depends on the mile traveled variable.

The amount of miles traveled is the independent variable because the cost of the cab fare depends on it.
