Question

The population of a rural town is 250 people. It is expected that the population of the town will double every decade. Which function represents p(d), the population

after d decades?

a. p(d) = 2^d + 250
b. p(d) = 2(250)^d
c. p(d) = 250(2)^d
d. p(d) = 2d + 250

Answer 1

The answer is C. If we go with exponential growth (which population growth generally is), then 259 would come first as the amount of people that were originally there.
