Answer:
Number of Armadillo deaths that year = 2.
Explanation:
Using population formulas
Overall population growth = Births + Immigration - Emigration - Deaths
Overall population growth = 5
Births = 2
Immigration = 6
Emigration = 1
Deaths = ?
5 = 2 + 6 - 1 - Deaths
5 = 7 - Deaths
Deaths = 7 - 5 = 2.
Using mathematical interpretation
Let the initial number of armadillos be x.
In that 1 year,
two armadillo's are born into a population
Population of armadillos = (x + 2)
Then six armadillo's immigrate into the population
Population of armadillos = (x + 2) + 6 = (x + 8)
but one leaves to find an area with more food
Population of armadillos = (x + 8) - 1 = (x + 7)
if the overall population growth is five armadillo's how many armadillo's died during the year.
If the number of deaths = y
(x + 5) = (x + 7) - y
y = x + 7 - x - 5 = 2
number of deaths = 2.
Hope this Helps!!!
