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

### Instruction:
The news announced a $0.4 oil price rollback this Friday. Mr. Deane decided to only fill his gas tank with 10 liters of gas today and then another 25 liters on Friday. If the cost per liter of gas is $1.4 today, how much will Mr. Deane spend for his 35 liters of gas?

### Response:
 Bwana Deane atatumia $1.4/lita x lita 10 = $14 kwa lita 10 za mafuta leo.
Bei ya mafuta kwa kila lita siku ya Ijumaa itakuwa $1.4/lita - $0.4/lita = $1/lita.
Hivyo, atatumia $1/lita x lita 25 = $25 kwa lita 25 zilizobaki siku ya Ijumaa.
Hivyo, Bwana Deane atatumia jumla ya $14 + $25 = $39 kwa lita zake 35 za mafuta.
