Kathryn moved to a new city for the new job she had landed two weeks ago. Her rent was $1200, 1/2 of what she spent on food and travel expenses in a month. Luckily, she found a new friend Shelby, who moved in with her to share the rent. If her salary was $5000 per month, how much money remained after her expenses?
