This looks like a math problem.
Apparently the fish gains that same amount of weight as the food that is eaten. It seems odd that the fish will be fed every single hour during the 24-hour day, but that is the assumption I will make.
16 ounces = 1 lb.
15 + (5 * 24 * 2/16) = weight in lbs. after 5 days
7 * 24 * 2/16 = lbs. of food eaten in 7 days
I hope this helps.
