### Instruction:
 Bobby alitaka pancakes kwa kifungua kinywa. Mapishi kwenye sanduku yanatengeneza pancakes 21. Wakati alikuwa anakula pancakes 5, mbwa wake aliruka na kula 7 kabla ya kukamatwa. Bobby ana pancakes ngapi zilizobaki?


### Response:
 Bobby alikula pancakes 5, mbwa wake alikula 7 hivyo 5+7 = 12
Mapishi yanatengeneza pancakes 21 na 12 zilikula hivyo 21-12 = <<21-12=9>>9 pancakes zilibaki
