Apopulation of flies, p, over a given amount of time, x, is modeled by the expression p(1+r)xp(1+r)x .

note: r represents percentage rate as a decimal

what does each factor in the expression represent?

select each correct answer.

p represents the initial amount of flies in the population

p represents the amount of flies at a given time

(1+r)(1+r) represents a growth of the fly population

(1+r)(1+r) represents a decay of the fly population
