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

### Instruction:
Tara's taking a road trip for the weekend.  She drives for two days, stopping to fill up her gas tank each time from empty to full when she needs it.  She visits 4 different gas stations in total, with the price of gas being $3, $3.50, $4, and $4.50 respectively at each.  If Tara's car has a 12-gallon tank, how much does she spend on gas for her road trip?

### Response:
 Kituo cha kwanza ambapo Tara anasimama kinatoza $3 kwa galoni ya mafuta, hivyo kwa tangi lake la galoni 12 anatumia $12*3= <<12*3=36>>36.
Kituo cha pili ambapo Tara anasimama kinatoza $3.50 kwa galoni ya mafuta, hivyo kwa tangi lake la galoni 12 anatumia $12*3.5= <<12*3.5=42>>42.
Kituo cha tatu ambapo Tara anasimama kinatoza $4 kwa galoni ya mafuta, hivyo kwa tangi lake la galoni 12 anatumia $12*4= <<12*4=48>>48.
Kituo cha nne ambapo Tara anasimama kinatoza $4.50 kwa galoni ya mafuta, hivyo kwa tangi lake la galoni 12 anatumia $12*4.5= <<12*4.5=54>>54.
Sasa tukijua kiasi cha kila kituo, tunasoma $36+$42+$48+$54= <<36+42+48+54=180>>180 kwa jumla ya mafuta.
