The large tank has a flow rate of -6 gallons per minute, which means that 6 gallons per minute are being removed from the tank. After a period of 25 minutes, the amount of water removed from the large tank would be 25 * 6 = 150 gallons.
Starting with 250 gallons and removing 150 gallons, the amount of water left in the large tank would be 250 - 150 = 100 gallons.
Therefore, the integer that represents the amount of water left in the large tank after 25 minutes is 100. Therefore, the correct answer is 100.
Water flows back and forth between a small and large tank. When water is moving into a tank the flow rate is positive, and when water is moving from a tank the flow rate is negative. Each tank begins with 250 gallons of water. The flow rate for the large tank is recorded as –6 gallons per minute. After a period of 25 minutes, which integer represents the amount of water left in the large tank?
