Answer 1

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 = $\frac{\text{New value-old value}}{\text{old value}}\times 100$

$\frac{1048}{100}$ = $\frac{x-40,900}{40,900}$

$\frac{1048\times 40,900}{100}=x-40,900$

x = (1048 × 409) +40,900

x = 428632 +40,900

x = 469532

469,532 Americans were in prison for drug related offenses in 2015.
