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

### Instruction:
A family's water and electricity bills average $30 a month for the first 4 months and $24 a month for the last 2 months. If the family's bills were averaged over all 6 months, what would the average monthly bill be?

### Response:
 Bili za maji na umeme za familia zina wastani wa $30 kwa mwezi kwa miezi 4 na $24 kwa mwezi kwa miezi 2.
Jumla ya gharama ya bili zote ni 30*4 + 24*2 = <<30*4+24*2=132>>132 dola.
Bili ya kila mwezi ni 132/6 = <<132/6=22>>22 dola.
