I don't understand anything about this question:
In a pest eradication program, N sterilized male flies are released into the general population each day, and 90% of these flies will survive a given day.
In a pest eradication program, N sterilized male flies are released into the general population each day, and 90% of these flies will survive a given day.
A) Show that the number of sterilized flies in the population after n days is
N + (.9)N + (.9)2N + ... + (.9)n-1N
N + (.9)N + (.9)2N + ... + (.9)n-1N
B) If the long ranger goal (infinite) of the program is to keep 20,000 sterilized males in the population, how many such flies should be released each day?
