lucia's rent is $100 less than three times her car payment. If the total of the bills is $800, how much does she pay for rent?
--------------------------
Let car payment be "x".
Then rent is "3x+100"
-------------------------
EQUATION:
x + 3x+100 = 800
4x = 700
x = $175 (car payment)
3x+100 = 3*175+100 = $625 rent
