money

Hey everyone. I am a 16 year old girl and i am looking to make some extra money as I need 4000 dollars for this school trip i want to go on and a car as soon as i can after that. My family doesn’t have that much money and said that they will help where they can but i need to do most of this on my own. I have a part time job where I can make 100-500 dollars every two weeks (depending on how busy we are). I was just looking for little ideas on how i can make some extra money to go on this trip. Thank you
