Answer 1

To find the total change in the amount of water in the tank after 6 days, we can calculate the change for one day and then multiply it by the number of days.

In one day, the water tank decreases by 10 gallons every 3 hours. Since there are 24 hours in a day, there are 8 sets of 3 hours in one day. Therefore, the water tank decreases by 10 gallons every 8 sets of 3 hours.

To find the total change in one day, we can multiply the decrease per set by the number of sets. 10 gallons * 8 sets = 80 gallons.

Now, to find the total change after 6 days, we multiply the change in one day by the number of days. 80 gallons * 6 days = 480 gallons.

Therefore, the total change in the amount of water in the tank after 6 days is 480 gallons.
