Answer 1

405.26%

Explanation:

We have been given that in 1970 the male incarceration rate in the U.S. was approximately 190 inmates per 100,000 population. In 2008 the rate was 960 inmates per 100,000 population.

`\text{Percent increase}=\frac{\text{Final amount}-\text{Initial amount}}{\text{Initial amount}}* 100`

`\text{Percent increase}=(960-190)/(190)* 100`

`\text{Percent increase}=(770)/(190)* 100`

`\text{Percent increase}=4.052631578947* 100`

`\text{Percent increase}=405.2631578947\%`

`\text{Percent increase}\approx 405.26\%`

Therefore, the percent increase in the male incarceration rate during the given period is 405.26%.
