Answer: Population of Boomtown in next year = 3141
Population of Dullsville in next year = 2066
Step-by-step explanation:
i) Given: Current population of Boomtown is = 3000
growth rate = 4.7% = 0.047 [in decimal]
Growth in population in 1 year= (growth rate) x (Current population)
= 0.047 × 3000 =141
Population in next year = Current population + Growth in population in 1 year
= 3000 + 141 = 3141
Hence, population of Boomtown in next year = 3141
ii) Given: Current population of Dullsville is = 2000
growth rate = 3.3% = 0.033 [in decimal]
Growth in population in 1 year= (growth rate) x (Current population)
= 0.033 × 2000 =66
Population in next year = Current population + Growth in population in 1 year
= 2000 + 66= 2066
Hence, population of Dullsville in next year = 2066
