Franco Township is also in Dorado County. Franco Township's population is about 30% greater than Emerson Township's, and its area is 512 square miles. What is the population density of Franco County?

If necessary, round your answer to the nearest whole number.

Answer 1

Density of population = total population / area of the township

Emerson township:
Population of Emerson = 6720 * (1/4)
= 1680
Density of population = 1680 /344
= 5 per square miles

Franco township:
30% of 1680 = 0.3 * 1680 = 504
Population = 1680 + 504
= 2184
Density = 2184/512
= 4 per square mile
