The population of a town is 9,200. It grows by 5% every year. What will the population be after 2 years?

💡 Solution & Explanation

Each year's growth is on the new population. After 1 year: 9,200 × 105/100 = 9,660. After 2 years: 9,660 × 105/100 = 10,143. Adding 10% of the original once gives 10,120, which forgets the growth on the first year's increase.
