Question

The population of a city is increasing at a rate of 3% per year. Which equation could be used to find the time, t, in years, that it will take the population of the city to go from 1,000 people to at least 2,000 people? a. 1.03t ≥ 2 b. 1,000 ≤ 1.03t c. 21.03t ≥ 2,000

Answer 1

B. This is because 2000-1000 is 1000. That means the population must grow by 1000. The rate at which the population is growing in terms of t is 1.03t. This means 1.03t has to equal more than a 1000. That is B
