The number of dolphins varies directly as the number of tuna. The number of tuna changes by a factor of 16/125, so the number of dolphins changes be a factor of 16/125.
The number of dolphins varies inversely as the square of the number of sharks. The number of sharks changes by a factor of 2/5, so the number of dolphins changes by a factor of (5/2)^2 = 25/4.
ANSWER: (50)(16/125)(25/4) = 40
