a) An environmental study in a community shows that the pollution level of a certain pollutant in the air increases by [math]

b)Census data for the community shows that the population of the community is increasing by [math]

c) Therefore this pollutant is increasing at a rate of [math]

If pollutant level is measured by the variable L, the population is measured by the variable P, and time by t, and the standard units are units and units of people are "h" (humans), then rewrite each of these sentences in Leibniz derivative notation:

a)

b)

c)
