Alright, people! Couple weeks ago a co-worker asked me to give her daughter french lessons. I was sure if I wanted to do it but know I made up my mind. The only thing is I don't know how much I should charge her. She said to wait until her daughter is in summer vacation, so I still got some time. But basically I am going to give three 1-hour lessons per week. How much should I charge her? On a weekly basis or hourly basis?
