Create your own population growth model word problem for a classmate to solve.

1) Describe your population growth scenario in at least two paragraphs to give context for the math problem. For example, it could be the change in the prairie dog population each month in the open space across from your house or it could be the population size of infected people during the spread of an infectious disease.

2) Explicitly state your population growth model and include the following:

Initial population size, P₀

Population size after one growth period, P₁(i.e., days, months, or years)

Average change between growth periods, d

Growth model equation of the form P_n= P_(n-1)+ d
