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

### Instruction:
A pen costs $9 more than a pencil. If a pencil costs $2, find the total cost of both items.

### Response:
 Penseli inagharimu $2.
Kalamu inagharimu $9 zaidi ya penseli, hivyo $9 + $2 = $<<9+2=11>>11.
Hivyo gharama ya jumla ya vitu vyote ni $2 + $11 = $<<2+11=13>>13.
