Question

The bar graph shows that life​ expectancy, the number of years newborns are expected to​ live, in a particular region has increased dramatically since ancient times. Find the percent increase in average life expectancy of the region from the Stone Age to 2016.

Answer 1

Answer:

There was an increase of 176.92 % of life expectancy

Step-by-step explanation:

To find this solution, we need to compare the life expectancy in the Stone age and in 2016

Stone age

26 years. (this represents 100%)

2016

72 years

We apply a rule of three

26 years ------------------100%

72 years --------------------x

(72/26)*100% = 276.92 %

276.92 % - 100% = 176.92 %

There was an increase of 176.92 % of life expectancy
