Proof: Call the fish A-G and make all the prices into simple addition equations.
Add all the numbers and equations together. You get:
2(A+B+C+D+E+F+G) = 196.
(A+B+C+D+E+F+G) = 98
After that, add together the first, third, fifth, and seventh equations.
(A+B+C+D+E+F+G+A) = 110
And then subtract the last two equations I've written from each other, leaving...
A = 12.
After that, it's a matter of simple addition i know this is late
