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

### Instruction:
Benny has bought a new piggy bank and wants to start saving money. In January he adds $19, then adds the same amount in February. By the end of March, he has $46. How many dollars did he add to the piggy bank in March?

### Response:
 Mwezi Januari na Februari, Benny aliongeza $19 + $19 = $38 kwenye kibanda cha kuwekea akiba.
Tunajua kuwa mwishoni mwa mwezi Machi alikuwa ameokoa dola 46, hivyo mwezi Machi, aliokoa $46 - $38 = $8.
