A class of models for population growth rates in marine fisheries assumes that the harvest from
fishing is proportional to the population size. One such model uses the following quadratic function.
G = 0.3n − 0.2n²
Here G is the growth rate of the population, in millions of tons of fish per year, and n is the
population size, in millions of tons of fish.

Calculate G(1.61). (Round your answer to three decimal places.)

G(1.61) =
