Southern Grasshopper mice can be a major problem that reduce the population of grasshopper. Southern Grasshopper mice are preyed upon by hawks. A model for the predation rate (per capita) is given by R(d)=300d/(900+d2)
Where d is the density of Southern Grasshopper mice.
For which density of Southern Grasshopper mice is the per capita predation rate maximal?
