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

### Instruction:
 James alinunua galoni moja ya maziwa kwa $3, kundi la ndizi kwa $2, na alilipa kodi ya mauzo ya 20%. James alitumia pesa kiasi gani?


### Response:
 Kwanza jumlisha ununuzi wa James ambao ni $3 + $2 = $<<3+2=5>>5.
Hivyo, kiasi cha kodi ya mauzo ambayo James alilazimika kulipa ni $5 * .2 = $<<5*.2=1>>1.
Hivyo, James alitumia jumla ya $5 + $1 = $<<5+1=6>>6.
