A town has a population of 4000 and grows at 3.5% every year. To the nearest year, how long will it be until the population will reach 7500?

The correct answer is 25 years.

Step-by-step explanation: If the population increases by 3.5 %, and the population to start off with is 4,000, this means the population will increase by 140 people every year. (4,000 x 0.035 = 140) 140 x 25 = 3,500 thus 4,000 + 3500 = 7500 ... 25 years
