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

### Instruction:
Michael has $50. He wants to surprise his mom on Mother's day by buying a cake for $20, a bouquet for $36, and a set of balloons for $5. How much more money does Michael need to buy all those?

### 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.
