Question

A tank that is 40% full contains 648 gallons of water. How much water is in the tank when the tank is at full capacity (100%)?

Answer 1

Answer: 1620 gallons of water

Explanation:

Let the water that is in the tank when the tank is at full capacity be represented by x.

Therefore, 40% of x = 648

40% × x = 648

40/100 × x = 648

0.4 × x = 648

0.4x = 648

x = 648/0.4

x = 1620

The answer is 1620 gallons
