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=21-A

C=24-21+A

D=32-4-A

E=37-28+A

F=31-9-A

G=25-22+A

and A=26-3-?

my question is what variable goes where the ? is. i think its b but i'm not sure

**drwls**, Sunday, October 26, 2008 at 9:34amMany 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

**drwls**, Sunday, October 26, 2008 at 1:23pmCombining the last two equations gives you

G + A = (2 + A) + A = 26

2A = 24

Do you see it now?
