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

### Instruction:
Tony drives a car that gets 25 miles to the gallon.  He drives 50 miles round trip to work 5 days a week.  His tank holds 10 gallons.  He begins the week with a full tank and when he runs out he fills up at the local gas station for $2 a gallon.  How much money does Tony spend on gas in 4 weeks?

### Response:
 Tony anaendesha maili 50*2=<<50*2=100>>100 kwa siku kazini.
Anapita jumla ya maili 100*5=<<100*5=500>>500 kwa wiki.
Gari lake linapata maili 25*10=<<25*10=250>>250 kwa tangi.
Hivyo anahitaji kujaza mafuta kila 500/250=<<500/250=2>>2 wiki.
Anapoanza wiki na tangi kamili na anajaza mara 1 zaidi, hivyo anahitaji tangi 1+1=<<1+1=2>>2 za mafuta kwa mwezi.
Kila tangi inagharimu $2*10=$<<2*10=20>>20.
Hivyo kwa muda wa wiki 4 anatumia 4*20=$<<4*20=80>>80 kwa mafuta.
