1) Write a differential equation that models this situation. Let V represent the volume (in gallons) in the tank and t represent the time (in minutes). 2) Solve for the general solution (do not solve for V). 3) Use the initial condition to find the constant of integration, then write the particular solution (do not solve for V).

Question
Suppose the rate at which the volume in a tank decreases is proportional to the square root of the volume
present. The tank initially contains 25 gallons, but has 20.25 gallons after 3 minutes. Answer the
following.
