7-135.

Set up an equation to represent the following situation. Be sure to define your variables.

The rate at which a bucket leaks water, in $\text{cm}^3/\text{min}$, is directly proportional to the amount of water in the bucket at any given time.

In the function $y = kx$, $y$ is directly proportional to $x$.

Amount of water in bucket: $w(t)$

Rate bucket leaks:$\frac{dw}{dt}$
