### Instruction:
 Michael ana $42. Ndugu yake ana $17. Michael anampa nusu ya pesa kwa ndugu yake. Ndugu yake kisha ananunua pipi zenye thamani ya dola 3. Ndugu yake ana pesa ngapi, kwa dola, mwishoni?


### Response:
 Michael anampa 42/2=<<42/2=21>>21 dola.
Michael ana 42-21=<<42-21=21>>21 dola zilizobaki.
Kabla ya kununua pipi, ndugu yake ana 17+21=<<17+21=38>>38 dola.
Mwishoni, ndugu yake ana 38-3=<<38-3=35>>35 dola.
