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

### Instruction:
 Gretchen, Mitzi, na Beth walikwenda kucheza bowling pamoja. Gretchen alifunga alama 120. Mitzi alifunga alama 113. Beth alifunga alama 85. Alama ya wastani ya bowling yao ilikuwa ni ngapi?


### Response:
 Gretchen alifunga alama 120 + Mitzi alifunga alama 113 + Beth alifunga alama 85 = <<120+113+85=318>>318 alama zilizounganishwa.
Wastani wa alama zao zilizounganishwa za 318 / 3 wachezaji = <<318/3=106>>106.
