Buying a car on installments

Q: I had a question about buying a car on installments. There is a car the dealership is selling for 17,000 but if I don't have cash upfront then I'll have to buy it in installments. So now they will sell it to me for 20,000 because of the fact I don't have cash upfront so will this be getting involved with interest?

Copyright

Q: I am a student. I have few notes that are copyright and very expensive but  I have a copy of them. Can I sell copies at a low price as a lot of people are looking to buy them online and I need money for further studies?
