Question 02

The hours you stay awake is a function of the number of Monster drinks you have in the evening. Identify the dependent variable.

The number of Monsters

The hours awake

06

Question 03

If the dependent variable is the number of kilometers you can drive, and the independent variable is the amount of gas (measured in liters) in your car, write a sentence explaining the meaning of k(20) = 285.

With 285 liters, you can drive 20 kilometers

With 300 liters, you can drive 30 kilometers

With 20 liters of gas, you can drive 285 kilometers.

With 20 liters of gas, you can drive 255 kilometers.
