The number of state federal inmates in millions during year x, where x is greater than or equal to 2002 can be approximated by the following formula
N=0.04x78.96
Determine the year in which there were 1.2 million inmates

N = 1.2
1.2 = 0.04 x  78.96
OR
0.04 x  78.96 = 1.2
0.04 x = 1.2 + 78.96
0.04 x = 80.16 Divide both sides by 0.04
x = 80.16 / 0.04
x = 2004 
N=0.03x58.78

The number of state federal inmates in millions during year x, where x is greater than or equal to 2002 can be approximated by the following formula.
