Let $N(t)$ the number of individuals in a popuation at time $t.$ Suppose the birth rate in the population is $200$ and the death rate is $500,$ both measured as

numbers of individuals per individual per unit time. Suppose also that the net immigration rate is $6,700$ in numbers of individual per unit time.

Complete the following statement using $N$ rather than $N(t).$

$\frac{dN}{dt}=$
