The correct answer is -480 gallons.
To find the total change in the amount of water in the tank after 6 days, we need to calculate the change in gallons per day and then multiply it by the number of days.
The water tank decreases by 10 gallons every 3 hours. There are 24 hours in a day, so there are 8 sets of 3 hours in a day (24 divided by 3).
Therefore, the water tank decreases by 10 gallons every 8 sets of 3 hours, which means it decreases by 10 gallons every day.
After 6 days, the water tank would have decreased by 10 gallons/day * 6 days = 60 gallons.
So, the correct answer is 60 gallons.
