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

### Instruction:
 Bob na Kate walikwenda kwenye mgahawa kwa chakula cha jioni. Baada ya kumaliza kula, mhudumu aliwapa Bob bili ya $30 na Kate bili ya $25, lakini aliwaambia kuwa wanastahiki punguzo maalum; 5% kwa Bob, 2% kwa Kate. Kuzingatia punguzo hizo, wanapaswa kulipa kiasi gani jumla?



### Response:
 5% ya $30 ni (5/100)*$30 = $<<(5/100)*30=1.5>>1.5
Hii inamaanisha Bob atalipa $30-$1.5=$<<30-1.5=28.5>>28.5
2% ya $25 ni (2/100)*$25 = $<<(2/100)*25=0.5>>0.5
Hii inamaanisha Kate atalipa $25-$0.5=$<<25-0.5=24.5>>24.5
Jumla wanapaswa kulipa ni $28.5+$24.5=$53
