Question 785028: Suppose a bathtub contains 60,000 cubic inches of water. If water can be drained from the tub at a rate of 800 cubic inches per second, then w(t)= 60,000-800t represents the volume of water left in the tub after draining for t seconds.
The question is: After how many seconds will the tub be empty?

You can put this solution on YOUR website!
You have a linear function in one variable, and you want to know the value of the independent variable when the value of the function is 0.
w%28t%29=highlight%2860000-800t=0%29

60000=800t
600=8t
300=4t
150=2t
t=75
