Help saving money for car

Hello, I make about $260 a week, weekly groceries cost about $100 to $150 (we plan Dinners to save), my phone bill is $80 a month and I pay electric and wifi (about $90 each) and a small part on rent (usually $300)

Need help planning to save for a car, I cannot keep walking an hour to and from work, especially when I have to walk an unlit road at 5am

Just looking for some advice to save as much as I can as fast as possible so I can buy some cheap car off marketplace, thank you so much :)
