The amount of water in the pool after t minutes is modeled by the linear function
, hence it is a function of time.
A <em>linear function</em> for the amount of water in the pool, considering that it is <u>drained at a rate of a gallons per minute</u>, is modeled by:
![V(t) = V(0) - at](https://tex.z-dn.net/?f=V%28t%29%20%3D%20V%280%29%20-%20at)
- In which V(0) is the initial volume.
In this problem, draining her hot tub at a rate of <u>5.5 gallons per minute</u>, hence
, and:
![V(t) = V(0) = 5.5t](https://tex.z-dn.net/?f=V%28t%29%20%3D%20V%280%29%20%3D%205.5t)
Which is a function of time.
