Question
If a nation has an annual growth rate of 2 percent, its population will double inQuestion 7Answera.50b.35c.20d.70
Solution
The question seems to be referring to the "Rule of 70," which is a way to estimate the number of years it takes for a certain variable to double. The rule number (70 in this case) is divided by the growth rate to get the approximate number of years.
In this case, the growth rate is 2 percent. So, you would calculate 70 / 2 = 35 years.
So, the answer is b. 35.
