Let's write the number of liters in Bucket A as "a", he amount in Bucket B "b", and the amount in Bucket C "c". We can now write the following equations:
\(a + b + c = 17\)
\(a = 3b\)
\(c = b - 2.5\)
We can now use subsitution to solve for each of them.
\(3b + b + b - 2.5 = 17\)
\(5b = 19.5\)
\(\mathbf{b = 3.9}\)
So Bucket B has 3.9 liters.
