Answer:
The kingfish weighed 72 pounds, the amberjack weighed 36 pounds, the white marline weighed 144 pounds and the tarpon weighed 180 pounds.
Step-by-step explanation:
The following fish were caught:
Kingfish, amberjack and white marlin
Let a=pounds of kingfish, b=pounds of amberjack and c=pounds of white marlin and let d=pounds of tarpin
From the information we know that a=2b, c=2a, d=5*b
Let y= the total weighed fish = a+b+c = 252
Therefore we can write y in terms of a:
\(y=252=a+a/2+2*a\)
we can solve a which is:
\(a=252/3.5=72\)
we can solve b as \(b=a/2=72/2=36\) and therefore \(c=2*a=72*2=144\) and \(d=5*b=5*36=180\)
So then y= a+b+c = 72+36+144 = 252 pounds of fish
The kingfish weighed 72 pounds, the amberjack weighed 36 pounds, the white marline weighed 144 pounds and the tarpon weighed 180 pounds.
