Let R = minimum monthly revenue.
Taxes paid = 12% of R = .12R
Amount left = R - ,12R = 1R - .12R = 1.00R - .12R = (1.00 - .12)R = .88R
So Amount needed = $5500
Let 5500 = .88R
Divide both sides by .88
R = 5500/.88
[Note that dividing by a fraction less tha 1 gives you a result *larger* than your origial dividend, which makes sense here.]
R = $6250 minimum pre-tax income.
