Find an equation of the plane that is parallel to the line of intersection of the planes ( x + 3y + z = 3 ) ( 3x - y - z = 0 ) a
nd pass through the origin and point of intersection of the lines passes through the point of intersection of the lines ( x = ? = 2 + 2 ) and ( = y + 1 = 2 )
$17.49 because you multiply 22 by .25 getting 5.5. You subtract that from the original 22 getting 16.5 which you then multiply by the sales tax .06. Add the tax amount to the 16.5 to get 17.49.
