at the bottom. Oil is poured into the tank at a rate of 2.1 gallons per minute and the valve at the bottom empties the tank at a rate of 1.9 gallons per minute. If the tank does not fill until 12:00 noon the next day, how many gallons does the tank hold?

1440 minutes in a day.
1440 minutes X 2.1 gallons=3024 gallons poured over the day .
in that time 2736 gallons has come out of the bottom.
1440 minutes X 1.9 gallon= 2736 gallons.
difference is 288.
As mentioned probably would be better to close it , then fill unless this is not possible due to operational requirements.

How much time elapsed from when the oil was first poured into the tank and the valve at the bottom was opened?

From what I did I got 288 gallons.
The smart thing to do would be to close the valve at the bottom of the tank which would keep you from having to wait until the next day to find the answer.

That sounds like your math homework to me.
In the real world, the rate of drainage would
vary with the level of oil in the tank.

Or,2.1 minus 1.9 = .2 gpm, times 60=12 gph, times 24=288
That wasn't so hard, common, give me a hard question.
