Question

in june 2012, about 2.4 billion people used the internet - 100 times more than the number of people who used it in June 1995. If the growth in Interne usage is linear (arithmetic), about how many people were added on average each year from 1995 to 2012?

Answer 1

Answer:

About 139,764,705.9 users were added, on average, per year, from 1995 to 2012.

Step-by-step explanation:

The problem states that in june 2012, about 2.4 billion people used the internet - 100 times more than the number of people who used it in June 1995.

So, in June 2012, 2.4 billion people used the internet.

In June 1995, $\frac{2,400,000,000}{100} = 24,000,000$ = 24 million people used the internet.

About how many people were added on average each year from 1995 to 2012?

$2012 - 1995 = 17$. There were 17 years between 1995 and 2012.

$2,400,000,000 - 24,000,000 = 2,376,000,000$. There were  2,376,000,000 internet users added during this 17-year period. To find this number per year, we solve the following rule of three:

1 year - x users

17 years - 2,376,000,000 users

$17x = 2,376,000,000$

$x = \frac{2,376,000,000}{17}$

$x = 139,764,705.9$

About 139,764,705.9 users were added, on average, per year, from 1995 to 2012.
