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

### Instruction:
Julia has a parrot and a rabbit. She buys food for both of the animals for $30 in total a week. Julia has the rabbit for 5 weeks, and the parrot for 3 weeks. How much money did Julia already spend on food for her animals, if the weekly cost of the rabbit food is $12?

### Response:
 Gharama ya chakula cha sungura ni $30 - $12 = $18 kwa wiki.
Hivyo kwa wiki 3, Julia ameshatumia $18/kwa wiki * 3 wiki = $<<18*3=54>>54 kwa chakula cha sungura.
Julia amekuwa na kuku kwa wiki 5, hivyo ameshatumia $12/kwa wiki * 5 wiki = $<<12*5=60>>60 kwa chakula cha kuku.
Hii inamaanisha Julia ameshatumia jumla ya $54 + $60 = $<<54+60=114>>114 kwa chakula cha wanyama wake.
