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

### Instruction:
 Jim na binamu yake wako kwenye mgahawa. Kila mmoja wao ameagiza cheeseburger na milkshake. Pia, wamegawana chakula cha cheese fries. Cheeseburger ni $3. Milkshake ni $5. Cheese fries ni $8. Wametumia 80% ya pesa zao pamoja. Ikiwa Jim alileta $20, binamu yake alileta kiasi gani?


### Response:
 Wametumia $8 kila mmoja kwa cheeseburger na milkshake kwa sababu 3 + 5 = <<3+5=8>>8
Jumla wametumia $16 kwa vitu hivi kwa sababu 2 x 8 = <<2*8=16>>16
Wametumia $24 kwa chakula chao kwa sababu 16 + 8 = <<16+8=24>>24
Walikuwa na $30 mwanzoni kwa sababu 24 / .8 = <<24/.8=30>>30
Binamu yake alikuwa na $10 kwa sababu 30 - 20 = <<30-20=10>>10
