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

### Instruction:
The Indigo Restaurant receives 18 online customer reviews. They receive six 5-star reviews, seven 4-star reviews, four 3-star reviews, and one 2-star review. What is the average star rating for Indigo Restaurant based on these reviews?

### Response:
 Kwanza, hesabu idadi jumla ya nyota ambazo tathmini za nyota tano zinapokea kwa kuzidisha idadi ya tathmini na kiwango cha nyota: nyota tano * tathmini sita = 30 nyota.
Kisha rudia mchakato huo kwa tathmini za nyota nne: nyota nne * tathmini saba = 28 nyota.
Kisha rudia mchakato huo kwa tathmini za nyota tatu: nyota tatu * tathmini nne = 12 nyota.
Kisha rudia mchakato huo kwa tathmini ya nyota mbili: nyota mbili * tathmini moja = 2 nyota.
Sasa ongeza idadi jumla ya nyota ili kupata idadi jumla ya nyota kwa tathmini zote: 2 nyota + 12 nyota + 28 nyota + 30 nyota = 72 nyota.
Sasa gawanya idadi jumla ya nyota na idadi jumla ya tathmini ili kupata kiwango cha wastani cha nyota: 72 nyota / 18 tathmini = 4 nyota.
