Question: A population of 8,000 increases by 15% every year. What is the population after 2 years?
(a) 9,320
(b) 10,580
(c) 9,600
(d) 9,700


Solution:

After 1 year:
Population = 8,000 + 15% of 8,000 = 8,000 + 1,200 = 9,200.
After 2 years:
Population = 9,200 + 15% of 9,200 = 9,200 + 1,380 = 10,580.
