Question

Type in only your numerical answer to the following problem; do not type any words or letters with your answer. The population of Neverland was 2.3 billion, one hundred years ago. Currently, the population is 3.2 billion. What will this population be 100 years from now? NOTE: Round to the nearest tenth of a billion.

Answer 1

4.5 billion

Explanation:

`2.3(1+x/100)=3.2`

`1+x/100=3.2/2.3`

`x/100=32/23-1`

`x/100=0.39130434782`

`x=0.39130434782(100)`

`x=39.1304347826`

`3.2(1.39130434782)`

`4.45217391302`
