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

### Instruction:
Susan had a bouquet of 3 dozen roses.  She gave half to her daughter, and then placed the rest in a vase.  The next day, one-third of the flowers in the vase were wilted.  After removing the wilted flowers, how many flowers remained in the vase?

### Response:
 Kwa kuwa dazeni ina maua 12, Susan alikuwa na buketi ya maua 3*12=<<3*12=36>>36.
Alitoa nusu, 36/2=<<36/2=18>>18, kwa binti yake.
Hivyo, alibakiwa na 36-18=<<36-18=18>>18 maua.
Theluthi moja ya maua yaliyobaki yalikauka, hivyo 18/3=<<18/3=6>>6 yalikauka.
Baada ya kuondoa maua yaliyokauka, Susan alibakiwa na 18-6=<<18-6=12>>12 maua kwenye kikombe.
