The local fish market is having a sale on whole fish. the prices are as follows:
You can buy an albacore and a barracuda for$21
You can buy a barracuda and a carp for $24
You can buy a carp and a dogfish for $32
You can buy a dogfish and an eel for $37
You can buy an eel and flounder for $31
You can buy a flounder and a gar for $25
You can buy gar and an albacore for $26
Determine the cost of each individual fish
i understand that
B=21A
C=2421+A
D=324A
E=3728+A
F=319A
G=2522+A
and A=263?
my question is what variable goes where the ? is. i think its b but i'm not sure

math same question as before with new questions to  drwls, Sunday, October 26, 2008 at 9:34am
Many of your equations are wrong.
B = 21  A
C = 24 (21 A) = 3 + A
D = 32  (3 + A) = 29  A
E = 37  (29  A) = 8 + A
F = 31  (8 + A) = 23  A
G = 25  (23  A) = 2 + A
G + A = 26
The last two equations can be solved for A, which is 12

i still don't understand how you got 12, but thank you for your help!

Combining the last two equations gives you
G + A = (2 + A) + A = 26
2A = 24
Do you see it now?
