Math Problem Statement

The population of a community is known to increase at a rate proportional to the number of people present at time t. The initial population P0 has doubled in 5 years. Suppose it is known that the population is 8,000 after 3 years. What was the initial population P0? (Round your answer to one decimal place.) P0 =

Incorrect: Your answer is incorrect. What will be the population (in persons) in 10 years? (Round your answer to the nearest person.)

Incorrect: Your answer is incorrect. persons How fast (in persons/year) is the population growing at t = 10? (Round your answer to the nearest person.)

Incorrect: Your answer is incorrect. persons/year
