<human>:  There are 10000 gallons of water in a pool. Using a water pump, Anthony and his father fill a tank with half the amount of water in the pool. They use water from the tank to water their vegetable garden. If the tank is emptied at a rate of 500 gallons of water per day, how many gallons of water will be remaining in the tank after 6 days?
<bot>: How many gallons of water does the water pump take? ** The water pump takes 1/2 *10000 = <<5000=5000>>5000 gallons of the pool's water into the tank.
How many gallons of water will be used after six days? ** If 500 gallons of water is used daily for six days, the total amount of water used after six days is 500*6 = <<500*6=3000>>3000 gallons.
How many gallons of water will be remaining in the tank after 6 days? ** The total amount of water remaining in the tank will be 5000-3000 = <<5000-3000=2000>>2000 gallons
