Answer:
405.26%
Step-by-step 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.
[tex]\text{Percent increase}=\frac{\text{Final amount}-\text{Initial amount}}{\text{Initial amount}}\times 100[/tex]
[tex]\text{Percent increase}=\frac{960-190}{190}\times 100[/tex]
[tex]\text{Percent increase}=\frac{770}{190}\times 100[/tex]
[tex]\text{Percent increase}=4.052631578947\times 100[/tex]
[tex]\text{Percent increase}=405.2631578947\%[/tex]
[tex]\text{Percent increase}\approx 405.26\%[/tex]
Therefore, the percent increase in the male incarceration rate during the given period is 405.26%.
