A population of 30 deer are introduced into a wildlife sanctuary. It is estimated that the sanctuary can sustain up to 600 deer. Absent constraints, the population would grow by \( 60 \% \) per year. Estimate the population after one year \( p_{1}=\square \) Estimate the population after two years \( p_{2}=\square \) Question Help: D Post to forum
