How many rabbits will a fertile pair produce in one year? ...in three years?

Question

If rabbits have a one month gestation period, are fertile after 4 months (and within minutes after giving birth), and have an average of 7 kits per litter, how many rabbits will a fertile adult pair produce in a year?  Assume no deaths, maximum fertility, and a 1-to-1 male/female average.

 

How many rabbits will be produced in 3 years?

 

How would I set up this equation for X years?  

 

Is it also possible to assume a 40% mortality rate after M months?

 

 

Answer 1

This may not be what you want but the problem seems simple enough. The question is how many rabbits will one fertile pair produce in a given time period. The only relevant information is the one-month gestation period and the pair is fertile immediately after birth. If the pair breeds immediately after each birth, they will produce 7 rabbits every month. or 12 x 7 = 84 per year.

 

Given the wording of the problem, it only asks about the production of a single fertile pair. All other information is a red herring.
