Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
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?

### Response:
 Wakati rafiki yake alihama na kugawana gharama za kodi ya nyumba naye, Kathryn alianza kulipa 1/2*1200 = $600 kwa gharama za kodi ya nyumba.
Gharama zake za chakula na usafiri kwa mwezi ni 1200*2 = <<1200*2=2400>>2400.
Jumla ya gharama za kila mwezi anazozilipa ni 2400+600 = <<2400+600=3000>>3000.
Mshahara wake ni $5000, hivyo anabaki na $5000-$3000 = $2000 baada ya gharama zake.
