Question

Suppose the population of a town is 15,200 and is growing 2% each year. a. Write an equation to model the population growth. b. Predict the population after 10 years.

Answer 1

Try simplifying the number to start. For example, if the population of the town is 100 people and the population growth is 2%, then there will 102 people in the town next year (Y=1). Continue adding 2% to the population for each of 10 years to get the answer for the 10th year. Growth would be considered 100% of current population plus 2% additional for a total of 102% - convert 102% to to a factor and you will have your formula Y=15,200*1.02;18,529
