The weight of the heaviest fish is 15.2 pounds
•since the average is 13.2, we will multiply 13.2 by 5 because there is 5 total fish. this makes a total of 66 pounds between the 5 fish. then we will subtract the weights of the 4 fish given to us from the total of 66, to get the remaining weight of 15.2 pounds. that also happens to be the heaviest weight, so 15.2 is the correct answer
