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

### Instruction:
 Darla anahitaji kulipa $4/kilowati ya umeme kwa umeme wa 300 kilowati, pamoja na faini ya $150 ya kuchelewa. Analipa kiasi gani jumla?


### Response:
 Kwanza tafuta gharama ya jumla ya umeme: $4/kilowati * 300 kilowati = $<<4*300=1200>>1200
Kisha ongeza faini ya kuchelewa: $1200 + $150 = $<<1200+150=1350>>1350
