During one year, eight turtles are born into a population. Ten turtles immigrate into the population, but two emigrate to find mates.

If the overall population growth is nine turtles, what was the death rate of turtles during the year?

Use this formula:
population growth = (birth rate + immigration) – (death rate + emigration)

7
9
11
29

Answer:

death rate is 7

Step-by-step explanation:

population growth = 9

birth rate = 8

immigration = 10

death rate = x

emigration 2

population growth = (birth rate + immigration) – (death rate + emigration)

9 = (8+10) - (x+2)

9= 18 - (x+2)

-9 = - (x+2)

-9 = -x -2

-7 = -x

7 = x

death rate is 7
