Question

Today, a tank contains 6,600 gallons of water. For the past three days, 210 gallons of water was pumped out of the tank each day. What was the volume of the water in the tank three days ago

Answer 1

The volume of water in the tank three days ago is 5,970 gallons.

Step-by-step explanation:

To find the volume of the water in the tank three days ago, we need to subtract the total amount of water pumped out in the past three days from the current volume of the tank. Since 210 gallons of water was pumped out each day for three days, the total amount of water pumped out is 210 gallons/day x 3 days = 630 gallons. Therefore, the volume of water in the tank three days ago is 6,600 gallons - 630 gallons = 5,970 gallons.
