Population Growth

Question 18 • Modern Math KHS

Twenty years ago a small town in Texas had a population of 10,000. The population has increased 8% each year since then. Predict what the population of the town will be in 10 more years.

Answer
A
In 10 more years the population of this town will be approximately 21,589
B
In 10 more years the population of this town will be approximately 100,626
C
In 10 more years the population of this town will be approximately 123,794
D
In 10 more years the population of this town will be approximately 81,966

Explanation

The population grows for 30 years total: the 20 years already passed plus 10 more years. With 8% annual growth, use compound growth: 10,000 × (1.08)^30 ≈ 100,626. So the predicted population is approximately 100,626, choice B.
