### Instruction:
 John ananunua kibarfi kwa kutumia robo 4, dimu 3, na senti 5. Alipata senti 4 kama mabadiliko. Kibarfi kiligharimu senti ngapi?


### Response:
 Alitoa robo 4 ambazo ni $0.25 kila moja hivyo ni 4*0.25 = $<<4*0.25=1>>1
Alitoa dimu 3 ambazo ni $0.10 kila moja hivyo ni 3*0.10 = $<<3*0.10=0.30>>0.30
Robo, dimu na senti zilizochangia ni $1.35 na alipata senti 4 kama mabadiliko jumla ya $1.35- 4 = $1.31
