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

### Instruction:
 Michael ana $50. Anataka kumshangaza mama yake siku ya Mama kwa kununua keki kwa $20, buketi kwa $36, na seti ya mabaluni kwa $5. Anahitaji pesa ngapi zaidi ili kununua vyote hivyo?


### Response:
 Michael atatumia $20 + $36 + $5 = $<<20+36+5=61>>61.
Hivyo, anahitaji $61 - $50 = $<<61-50=11>>11 zaidi ili kununua vyote hivyo kwa mama yake.
