For two species A and B in competition, the carrying capacities, competition coefficients, per capita growth rate and population size are

KA = 1000           KB = 1200    α of B= 1     β of A= .5       rB= .5         r A= .3                

AN= 500                  BN= 200

According to the Lotka-Voltera model, what is growth rate of species A?
