Olivia walks up to a tank of water that can hold up to 50 gallons. When it is active, a drain empties water form the tank at a constant rate. When Olivia first sees the tank, it contains 38 gallons of water. Four minutes later, the tank contains 18 gallons of water.

b.) How many more minutes will it take for the tank to drain completely?

c.) How many minutes before Olivia arrived was the water tank completely full?

Answer:

Explanation:

I got the answer C because if the estimated value of the tank is 50 and it gets drained it will only have 18 gallon in it
