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, and Beth went bowling together. Gretchen bowled a 120. Mitzi bowled a 113. Beth bowled an 85. What was their average bowling score?

### 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.
