The growth of the rabbit populations on two farms is shown in the graphs below.



Compare the average growth per year of the populations of rabbits on both farms over the first 2 years.

A) Over the first 2 years, the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 12 rabbits per year.

B) Over the first 2 years, the average rate of population growth of rabbits in farm B is greater than average rate of population growth of rabbits in farm A by about 12 rabbits per year.

C) Over the first 2 years, the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 6 rabbits per year.

D) Over the first 2 years, the average rate of population growth of rabbits in farm B is greater than average rate of population growth of rabbits in farm A by about 6 rabbits per year.

Answer 1

step 1
Find the average growth per year of the populations of rabbits farm A
Over the first 2 years
for t=0
numbers of rabbits=5 (is not exact)
for t=2
numbers of rabbits=40
average=[40-5]/2---------> 17.5

step 2
Find the average growth per year of the populations of rabbits farm B
Over the first 2 years
for t=0
numbers of rabbits=5 (is not exact)
for t=2
numbers of rabbits=30
average=[30-5]/2---------> 12.5

step 3
Compare the average growth per year of the populations of rabbits on both farms

farm A=17.5
farm B=12.5
the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 5 rabbits per year.

therefore

the answer is the option C)
the average rate of population growth of rabbits in farm A is greater than average rate of population growth of rabbits in farm B by about 6 rabbits per year.
