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

### Instruction:
 Mary alikwenda dukani kununua matunda. Tofaa lina gharama ya $1, machungwa lina gharama ya $2, na ndizi lina gharama ya $3. Kwa kila matunda 5 ambayo wateja wanayanunua, duka linatoa punguzo la $1. Mary ananunua tofaa 5, machungwa 3, na ndizi 2. Atalipa kiasi gani?


### Response:
 Kwa tofaa, Mary atalipa 5 * $1 = $<<5*1=5>>5
Kwa machungwa, atalipa 3 * $2 = $<<3*2=6>>6
Kwa ndizi, atalipa 2 * $3 = $<<2*3=6>>6
Jumla ya gharama ya matunda kabla ya punguzo ni $5 + $6 + $6 = $<<5+6+6=17>>17
Kwa kuwa Mary amenunua 5+3+2 = <<5+3+2=10>>10 matunda, anastahili punguzo.
Punguzo ni 10/5 = $<<10/5=2>>2
Mary atalipa $17 - $2 = $<<17-2=15>>15
