Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
 Mama ya Josh anampa $20 ili aende kununua vitu dukani. Ananunua kofia kwa $10 na kalamu kwa $2. Kisha ananunua mikate minne. Kama kila mkate unagharimu $1.25, Josh anabakiwa na pesa kiasi gani?


### Response:
 Baada ya kununua kofia, Josh anabakiwa na $20 - $10 = $<<20-10=10>>10
Baada ya kununua kalamu, Josh anabakiwa na $10 - $2 = $<<10-2=8>>8
Gharama jumla ya mikate ni 4 * $1.25 = $<<4*1.25=5>>5
Baada ya kununua mikate, Josh anabakiwa na $8 - $5 = $<<8-5=3>>3
