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

### Instruction:
 Frank na Bill wana $42 na walinunua pizza 3 kubwa kwa pesa hizo. Kila pizza iligharimu $11 na Frank alilipa kwa pizza zote tatu. Frank alimpa Bill pesa zake zilizosalia. Ikiwa Bill alikuwa na $30 tayari, Bill ana pesa ngapi sasa?


### Response:
 Gharama jumla ya pizza ilikuwa 3 x $11 = $<<3*11=33>>33
Baada ya kulipa pizza, Frank alikuwa na $42 - $33 = $<<42-33=9>>9 zilizosalia
Bill sasa ana $30 + $9 = $<<30+9=39>>39
