### Instruction:
 Darwin ana 600$. Alitumia 1/3 yake kwa mafuta ya gari lake, na 1/4 ya kilichobaki kwa chakula. Alikuwa na pesa ngapi zilizobaki?


### Response:
 600/3=<<600/3=200>>200$ kwa mafuta
Baada ya kununua mafuta, Darwin ana 600-200=<<600-200=400>>400$ zilizobaki
400/4=<<400/4=100>>100$ kwa chakula
Darwin ana 400-100=<<300=300>>300$ zilizobaki
