Question

A population of moose on avalon peninsula numbered 80 individuals in 2013. in the next year, 21 individuals were born, 12 died, 7 emigrated out of the peninsula and 6 immigrated in. the population thus grew by ____.

Answer 1

The population grew by 8, or 10%.

The gains from births and immigrating in were 21+6=27.  The losses from deaths and emigrating out are 12+7=19.  (Since it is a loss, it will be -19.)

27-19 = 8 total gained; 8/80 = 1/10 = 10%

Answer 2

Answer:

it would be 88 or increased

Step-by-step explanation:

This is because, the equation for this is

(birth rate + Immigrated) - (death rate + emigrated)

   21         +        6            -          12        +           7

           27                          -                19

you would then add the 8 to get 88 which mean the population would have overly increased
