It will take 10 minutes to fill the tank completely.

Step-by-step explanation:

If the 30-gallon tank already has 3 gallons of water in it, then 27 more are needed to fill the tank.  Thus, at time t = 0, g(0) = 3 gallons, and

g(t) = (3 gallons) + (2.7 gal/min)t, where t is the time in minutes.

At the time the tank is completely full, it holds 30 gallons.  How long does this take to achieve:  Set (3 gallons) + (2.7 gal/min)t equal to 30 gallons:

30 = 3 + 2.7t, or 27 = 2.7t, or t = 10 minutes

It will take 10 minutes to fill the tank completely.
