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

### Instruction:
 Marcia anataka kununua matunda. Tofaa lina gharama ya $2, ndizi lina gharama ya $1, na machungwa lina gharama ya $3. Ikiwa Marcia ananunua tofaa 12, ndizi 4 na machungwa 4, ni kiasi gani cha wastani cha kila kipande cha matunda kwa dola?


### Response:
 Pata bei ya kila kundi la matunda
Tofaa 12 * $2 kwa tofaa = $<<12*2=24>>24
Ndizi 4 * $1 kwa ndizi = $<<4*1=4>>4
Machungwa 3 * $4 kwa machungwa = $<<3*4=12>>12
$24 + $4 + $12 = $<<24+4+12=40>>40 jumla ya pesa iliyotumika
12 + 4 + 4 = <<12+4+4=20>>20 jumla ya matunda yaliyonunuliwa
$40 / 20 matunda = $<<40/20=2>>2 kwa kila tunda
