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

### Instruction:
Frank and Bill have $42 and they bought 3 large pizzas with the money. Each pizza cost $11 and Frank paid for all three pizzas. Frank gave the rest of his money to Bill. If Bill had $30 already, how much money does Bill have now?

### 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
