I should I be dividing up my income?

Hey hey!

I (21F) have just secured my first job in a year (personal health reasons) and I'm looking to start saving and getting an idea of what my income split %'s should be!

Positives:
-Indianapolis, IN
-14$/h full time hours (after training)
-100$/M in rent currently to folks to live at home / gas / electric
-Parents both have LITERALLY NO CREDIT SCORE and have only paid in cash their entire life, obviously I have no debt
-Main priority in future apartment is affordability
-Some sort of car to take me from A to B

Negatives:
-No savings atm
-Lower class upbringing, low/no financial help from parents/family expected

If I forgot anything, please let me know! I'm an open book
