### Instruction:
 Mama wa Lizzy alimpa senti 80 na baba yake alimpa senti 40 kwa kushika ahadi yake. Alikwenda kwa mjomba wake na kutumia senti 50 kununua pipi kwa binamu yake mdogo. Mjomba wake alimpa senti 70 zaidi. Ana senti ngapi sasa?


### Response:
 Lizzy alipokea senti 80 + 40 = <<80+40=120>>120 kutoka kwa mama yake na baba yake.
Ametumia senti 50 kununua pipi, akibakiwa na 120 - 50 = 70 senti.
Mjomba wake alimpa senti 70 zaidi, jumla ya senti 70 + 70 = <<70+70=140>>140.
