S represents the sum of the weights of n fish in pounds. Which of the following represents the average (arithmetic mean) of the n weights in ounces? (1pound = 16 ounces)

As the sum of n fish in pounds is S pounds and 1 pound = 16 ounces then the sum of n fish in ounces will be 16S ounces.

So, average wight of n fish in onces is average=(sum of weights is ounces)/(# of fish)=16S/n.

Hope it's clear.

It's very clear. Not sure why this one even held me up. Think it was one of those long study nights where even the mundane and easy seem like a never ending brick wall that you are trying to climb. Thanks Bunuel. +1 buddy and kudos.

average = s/n

in ounce, the average = $$(s*16)/n$$

Bunuel, how can we plug in numbers for this one? This one looks simple, but for some reason, I'm having a hard time seeing if I'm doing it correctly...

Is this right?
n = 3 (for 3 fish)
s = 3 (each fish to weight 1 pound each. There are 3 fish so this equals to 3 pounds (total)).

Plugging into answer choice B) 16(3)/3 = 16 (since 16 is the average weight of the fish in ounces).
