Answer:

a. The 0.3 means that the population is growing by 30% each decade. The 100,000 means that the population is 100,000 in 1970.

b. The equation for the population y years after 1970 is

p(y) = 100,000 (1 + 0.3)^1/12

c. The equation for the population e centuries after 1970 is

p(e) = 100,000 (1 + 0.3)^10

P.S. Probably right, an exercise to you, to check.
