### Instruction:
 Nancy ana mkoba unaotunza chips za tortilla 22. Anampa chips 7 kwa ndugu yake na chips 5 kwa dada yake, akibaki na zilizobaki kwa ajili yake. Nancy alibakiwa na chips ngapi kwa ajili yake?


### Response:
 Idadi ya chips kabla ya kumpa yeyote ni 22.
Alimpa 7 kwa ndugu yake, hivyo alibakiwa na 22-7 = <<22-7=15>>15 chips.
Kisha alimpa 5 zaidi kwa dada yake, hivyo alibakiwa na 15-5 = <<15-5=10>>10 chips.
