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

### Instruction:
The math teacher would be happy if the class average test score was at least 85. There are 10 students in the class, 5 of which scored a 92 on the test and 4 of which scored an 80. What would the last student have to score to at least make the teacher happy?

### Response:
 Wanafunzi 5 walipata jumla ya alama 92 * 5 = <<92*5=460>>460
Wanafunzi wengine 4 walipata jumla ya alama 80 * 4 = <<80*4=320>>320
Jumla ya alama za wanafunzi 9 ni 460 + 320 = <<460+320=780>>780
Tunajua jumla ya alama za wanafunzi 10 lazima iwe angalau wastani wa 85 * wanafunzi 10 = <<85*10=850>>850
Hivyo, mwanafunzi wa mwisho anapaswa kupata angalau alama 850 - 780 = <<850-780=70>>70
