Provide an appropriate response.Suppose the number of fleas N (in thousands) in a given area is related to the number of pounds of insecticide x sprayed on the nesting areas according to Nx - 9x + N = 250. Find , the rate of change of the number of fleas with respect to the number of pounds of insecticide.

What will be an ideal response?
