Hello there! The answer is C.
So the equation is y = 14.08 ⋅ 2.08^x, where x stands for the number of years. You are finding the number of fish after five years, so place five in for x and solve.
y = 14.08 ⋅ 2.08^5 - Start by finding 2.08 to the 5th power. (I rounded off some decimal points since it was too long.)
y = 14.08 x 38.9329 - Next: multiply your two numbers.
y = 548.175232, or C since it is the closest whole number.
