Question

Maddi needs to rent a car.the rental costs$13 per hour Plus a processing fee of 100$. Which is the independent variable costs or time.

Answer 1

The independent variable is time.

Explanation:

(Y=mx+b format)

Maddi's rental for the car costs $13 per hour so the x variable would be the hours (x=hour). This would be a Y= mx + b equation and in this case, Y=13x + 100. Independent means (mathmatically) a variable that does not depend on any other variable for its value. The costs is always changing being dependent on the time portion. The time isn't dependent on anything. Thus, the independent variable is time.

(If you need a starting point which is b, it would be the $100 as the processing fee.)
