Q:
# 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 ____.

Accepted Solution

A:

The population grew by 8, or 10%.

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

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

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

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