posted by Jolic on .
The number N of state and federal inmates in millions during year x, where x is greater then but equal to 2002 can be approximated by the following formula.
N=0.04x78.48
Determine the year in which there were 1.8 million inmates.

1.8=.04x78.48
add 78.48 to both sides.
divide both sides by .04
