Pail C has thrice as much water as Pail B. If Dylan adds 0.5 ℓ of water to Pail C and 2.2 ℓ of water to Pail B, both pails will have the same volume of water. Find the volume of water in Pail C at first.

B |
C |
| Before |
1 u |
3 u |
| Change |
+ 2.2 |
+ 0.5 |
| After |
1 u + 2.2 |
3 u + 0.5 |
Both pails have the same volume of water in the end.
3 u + 0.5 = 1 u + 2.2
3 u - 1 u = 2.2 - 0.5
2 u = 1.7
1 u = 1.7 ÷ 2 = 0.85
Volume of water in Pail C at first
= 3 u
= 3 x 0.85
= 2.55 ℓ
Answer(s): 2.55 ℓ
