 Gari jipya la Ben lina gharama mara mbili ya gari lake la zamani. Aliuza gari lake la zamani kwa $1800 na akatumia hiyo kumalizia sehemu ya gharama ya gari lake jipya. Bado anadaiwa $2000 nyingine kwenye gari lake jipya. Gari lake la zamani liligharimu kiasi gani, kwa dola?


### Response:
 Gari lake jipya lina gharama ya 1800+2000=<<1800+2000=3800>>3800 dola.
Gari lake la zamani liligharimu 3800/2=<<3800/2=1900>>1900 dola.
