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

### Instruction:
 Papi Calot alijiandaa kupanda viazi katika bustani yake. Alipanga kupanda safu 7 za mimea 18 kila moja. Lakini bado ana nafasi kidogo, kwa hivyo anafikiria kuongeza mimea 15 ya viazi. Anapaswa kununua mimea mingapi Papi Calot?


### Response:
 Kwanza, hebu tuhesabu idadi ya mimea ambayo Papi alikuwa ameipanga: safu 7 * mimea 18/safu = <<7*18=126>>126 mimea
Sasa hebu tuongeze mimea mingine: mimea 15 + mimea 126 = <<15+126=141>>141 mimea
Hivyo, Papi anapaswa kununua mimea 141.
