Determine the initial value and the rate of change in the following description. A 2,000-gallon tank is half full with 1,000 gallons of water. Water is being pumped into the tank at a rate of 15 gallons per minute.

The initial value is b= , and the rate of change is m=

The initial value is 1,000 gallons, and the rate of change is 15 gallons per minute.

So, the initial value is b = 1000 gallons and the rate of change is m = 15 gallons per minute.
