Crop yield (tons ha(^{-1})) in response to nitrogen fertilizer \(N\) (kg ha(^{-1})) is modelled by \(Y(N) = -0.02N^{2} + 1.2N\). The market price of the crop is \$200 per ton and the cost of fertilizer is \$0.5 per kg. Environmental regulations limit nitrogen application to a maximum of 80 kg ha(^{-1}).
