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

### Instruction:
Kim orders a $10 meal and a drink for 2.5.  She gives a 20% tip.  She pays with a $20 bill.  How much does she get in change?

### Response:
 Bahasha inakuja kwa 10*.2=$2.
Hivyo jumla ya gharama ni 10+2.5+2=<<10+2.5+2=14.5>>14.5.
Hii inamaanisha atapata 20-14.5=$<<20-14.5=5.5>>5.5 kama mabadiliko.
