Question 39934: David helped his father stock the pond with fish. They put in baby catfish and bluegill. They put in a total of 75 fish. If the # of bluegill was doubled & the number of catfish was trippled there would be 175 fish in the pond. how many catfish were put in the pond?
Thank you Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Let b be the number of bluegill and c be the number of catfish.
Thus
b + c = 75 and
2b + 3c = 175
Now double the first equation and subtract it from the second...we get
2b + 3c = 175
-(2b + 2c = 150)
and we get
c = 25 catfish
