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

### Instruction:
Mrs. Brown paid her utility bills with 3 $50 bills and 2 $10 bills. How much are her utility bills?

### Response:
 Noti 3 za $50 zinafikia $50 x 3 = $<<50*3=150>>150.
Noti 2 za $10 zinafikia $10 x 2 = $20.
Hivyo, gharama ya bili za matumizi ya Bi. Brown ni $150 + $20 = $<<150+20=170>>170.
