Question: A tank with a capacity of 8000 gallons is 3/4 full. Daxton empty's the tank by 40% of the total volume of water in the tank to water his vegetable farm. He then fills the tank with 30% of the volume of water remaining in the tank. Calculate the final volume of water in the tank. Think carefully first, then make a decision:
The volume of water that is in the tank initially is 3 / 4 * 8000 = 6000 gallons. When Daxton empties 40% of the water, he pumps out 40 / 100 * 6000 = 2400 gallons of water. The total volume of water remaining in the tank is 6000 - 2400 = 3600 gallons. Daxton then fills the tank with 30 / 100 * 3600 = 1080 gallons of water. The final volume of water in the tank is 3600 + 1080 = 4680 gallons. So the answer is 4680.
