A town has a population of 12,000 and grows at 3.5% every year what will be the population after seven years

15,267

Step-by-step explanation:

The population is multiplied by 1+3.5% = 1.035 each year. After 7 years, it will be multiplied by 1.035^7:

12,000*1.035^7 = 15,267

The population will be 15,267 after 7 years.
