How to fix my charger free and easy?

My iPhone 4s chargers wires were torn from the plug not completely but for the most part I would just buy one but I'm not yet old enough for a job and I'm broke. I would get my mom to buy one but ever since we got our financial problems she's been a real penny pincher so what I'm looking for is a free (or at least fairly cheap) ideas to reattach the wires in it

If you are old enough to have one of them you are old enough to take care of it. Do chores around the neighborhood for enough to buy a new charger OR do without the unit. For most of us a basic cellphone is all that is needed.
