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

### Instruction:
 Ruth alitengeneza sandwichi. Alila sandwichi 1 na akampa ndugu yake sandwichi 2. Binamu yake wa kwanza alifika na kula sandwichi 2. Kisha binamu zake wawili wengine walifika na kula sandwichi 1 kila mmoja. Zilisalia sandwichi 3. Ruth alitengeneza sandwichi ngapi?



### Response:
 Binamu zake Ruth walikula jumla ya sandwichi 2 x 1 = <<2*1=2>>2.
Hivyo kulikuwa na sandwichi 3 + 2 = <<3+2=5>>5 kabla binamu zake hawajafika.
Kabla binamu yake wa kwanza hajafika, kulikuwa na sandwichi 5 + 2 = <<5+2=7>>7.
Ruth na ndugu yake walikuwa na sandwichi 1 + 2 = <<1+2=3>>3 pamoja.
Hivyo, Ruth alitengeneza sandwichi 7 + 3 = <<7+3=10>>10.
