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

### Instruction:
Ruth prepared sandwiches. She ate 1 sandwich and gave 2 sandwiches to her brother. Her first cousin arrived and ate 2 sandwiches. Then her two other cousins arrived and ate 1 sandwich each. There were 3 sandwiches left. How many sandwiches did Ruth prepare?

### 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.
