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

### Instruction:
Carson runs a carpool for five of his friends. The five of them cover all the gas expenses to compensate Carson for his time. Their total commute is 21 miles one way, gas costs $2.50/gallon, Carson's car gets 30 miles/gallon, and they commute to work 5 days a week, 4 weeks a month. How much does each person pay toward gas monthly?

### Response:
 Kwanza tafuta idadi ya safari za kila mwezi: siku 5/kwa wiki * 4 wiki/kwa mwezi = 20 siku/kwa mwezi
Kisha umultiply umbali wa safari moja kwa njia mbili: maili 21 * 2 = 42 maili
Kisha umultiply idadi ya safari na umbali wa kila safari: 42 maili/safari * 20 safari = 840 maili
Kisha ugawanye idadi ya maili kwa matumizi ya mafuta ya gari: 840 maili / 30 maili/kigaloni = 28 kigaloni
Kisha umultiply idadi hiyo na gharama ya kila kigaloni ili kupata gharama jumla: 28 kigaloni * $2.50/kigaloni = $70
Kisha ugawanye gharama jumla kwa idadi ya marafiki ili kupata gharama kwa kila mtu: $70 / 5 watu = $14/kila mtu
