Answer:
 5,450,000
Step-by-step explanation:
The population can be modeled by an exponential function with a growth rate of 1% per month. The time of interest, 5 years, is 60 months.
__
 population = (initial value) × (1 + growth rate per month)^(months)
 p = 3,000,000 × (1.01^60) . . . . . . population in 60 months
 p ≈ 5,450,000 . . . . in 5 years
