First you would find the total weight of all the 5 fishes that were caught, since 12.3 pounds is the average. You would d this by multiplying 12.3 and 5
(12.3)(5)=61.5 pounds
Then in order to find the pound of the unknown fish, you would find the total of the pounds of the other fishes which is given o you in the table and then subtract it from 61.5 which is the total weight of all 5 fishes.
61.5-46.9=14.6 pounds
