Bucket E has five times as much water as Bucket D. If Xavier adds 0.7 ℓ of water to Bucket E and 2.1 ℓ of water to Bucket D, both buckets will have the same volume of water. Find the volume of water in Bucket E at first.
| |
D |
E |
| Before |
1 u |
5 u |
| Change |
+ 2.1 |
+ 0.7 |
| After |
1 u + 2.1 |
5 u + 0.7 |
Both buckets have the same volume of water in the end.
5 u + 0.7 = 1 u + 2.1
5 u - 1 u = 2.1 - 0.7
4 u = 1.4
1 u = 1.4 ÷ 4 = 0.35
Volume of water in Bucket E at first
= 5 u
= 5 x 0.35
= 1.75 ℓ
Answer(s): 1.75 ℓ
