Combined Volume Test

A tank is completely filled with water.  A pump is used to drain the tank.  The amount of water remaining in the tank is given by the equation y=600-25x, where x is the number of minutes since the pump started and y is the volume, in gallons, of water remaining in the tank.  In the equation, what are the meanings of the numbers 25 and 600?

• The number 25 is the number of minutes it will take to drain the tank, which holds 600 gallons of water.

• The number 25 is the rate of increase, in gallons per minute, of the flow from the tank, which holds 600 gallons of water.

• The number 25 is the rate of increase, in gallons per minute, in the volume of water in the tank, which started at 600 gallons.

• The number 25 is the rate of decrease, in gallons per minute, in the volume of water in the tank, which started at 600 gallons.
