<PRE><B>Question 567732</B>
In 2005, the number of federal hazardous waste sites in Cali was 3 less than twice the number of sites in Washington. How many hazardous waste sites were there in Washington if there were 21 such sites in Calif?
Equation:
c = 2w-3
21 = 2w-3
2w = 24
w = 12 (12 sites in Washington)
=====================
