Answer:
469,532 Americans
Step-by-step explanation:
The number of Americans in prison for drug related offenses from 1980 = 40,900
Percentage increase = 1048%
Let the number of people in prison for drug related offenses in 2015 be 'x'
Percentage increase = [tex]\frac{\text{New value-old value}}{\text{old value}}\times 100[/tex]
[tex]\frac{1048}{100}[/tex] = [tex]\frac{x-40,900}{40,900}[/tex]
[tex]\frac{1048\times 40,900}{100}=x-40,900[/tex]
x = (1048 × 409) +40,900
x = 428632 +40,900
x = 469532
469,532 Americans were in prison for drug related offenses in 2015.
