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

### Instruction:
 Luisa anaendesha maili 10 kwenda dukani, maili 6 kwenda dukani, maili 5 kwenda duka la wanyama, kisha maili 9 kurudi nyumbani. Galoni moja ya mafuta inaweza kutumika kuendesha maili 15. Ikiwa galoni moja ya mafuta inagharimu $3.50, ni gharama jumla ya mafuta kwa safari yote ya Luisa ni kiasi gani?


### Response:
 Luisa anaendesha jumla ya maili 10 + 6 + 5 + 9 = <<10+6+5+9=30>>30
Luisa anatumia galoni 30 / 15 = <<30/15=2>>2 za mafuta kwa safari yake
Gharama jumla ya mafuta kwa safari ya Luisa ni 2 * 3.50 = $<<2*3.50=7.00>>7.00
