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

### Instruction:
There are 10 students in a class. The average age of 9 of them is 8 years. By how many years will this average increase if the tenth student is (quite strangely) 28 years old?

### Response:
 Wanafunzi 9 wana umri wa wastani wa miaka 8 hivyo jumla ya umri wao ni 9*8 = <<9*8=72>>72 miaka
Mwanafunzi wa kumi mwenye umri wa miaka 28 atafanya jumla kuwa 72+28 = 100 miaka
Umri mpya wa wastani utakuwa 100/10 = <<100/10=10>>10 miaka
Hii ni tofauti ya miaka 10-8 = <<10-8=2>>2 zaidi ya wastani wa awali.
