Speeding ticket and improper lane usage ticket in alabama?

i got 2 tickets last night, 1 for going 48 in a 35 and another for improper lane usage? not sure what thats about because i only changed lanes 1 time and used my blinker, the cop said i was weaving in and out of traffic. does anyone know about how much improper lane usage cost in alabama? also i know i can go to traffic driving school to get a ticket taken off my record but will this take both the tickets off sense i got them at the same time? how does this work what all do i pay for? do i still have to pay for the tickets? how much does it all cost?
