## Question

###### When organic waste is dumped into a pond, the oxidation process that takes place reduces the pond's oxygen content. However, given time, nature will restore the oxygen content to its natural level. Suppose the oxygen content $t$ days after organic waste has been dumped into the pond is given by $$P=100\left(\frac{t^{2}+10 t+100}{t^{2}+20 t+100}\right)$$ percent of its normal level. Find $t$ corresponding to an oxygen content of $80 \%$ and interpret your results.
