The number N of state and federal inmates in millions during year x, where x>2002 can be approximated by the following formula.

Question

N = 0.05x - 98.45

Determine the year in which there were 1.9 million inmates.

Answer 1

N = 0.05x - 98.45 = 1.9 Million.
0.05x = 1.9 + 98.45 = 100.35
X = 2007.
