Answer:
0.45 liters
Step-by-step explanation:
Let the initial amount of water in the tank be x.
Then, the volume of water was 8 times as much as the initial volume, that is 8x.
Then, another 16.75 liters of water is added and the total volume of water is now 20.35 liters.
This means that the amount of water in the tank is now:
8x + 16.75 = 20.35
Let us find x:
8x = 20.35 - 16.75
8x = 3.6
x = 3.6/8 = 0.45 liters
There was 0.45 liters of water in the tank initially.
