Answer:
a.
[tex]3*x=100\\100/3=33.(3)\\\\[/tex]
And you can round 33.(3) to 33.
b.
[tex]4*x=100\\100/4=25\\\\[/tex]
and the final result is 25.
c.
[tex]7*x=100\\100/7=14.29\\\\[/tex]
And you can round 14.29 to 14.
Explanation:
First of all, you have to find how many times the growth rate would multiply to get closer to 100%. So if you multiply 3 times 33 you'll get 99. So, a population with an annual growth rate of 3% doubles roughly every 33 years.
This solution is just for annual growth rate that is one year long.
