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

### Instruction:
 Shane anapika sandwichi kwa ajili ya Boy Scouts. Ananunua pakiti 2 za mkate uliokatwa ambazo kila moja ina vipande 20, na pia ananunua pakiti 2 za jibini lililokatwa ambazo kila moja ina vipande 8. Shane atatengeneza sandwichi kadri anavyoweza kulingana na jibini alilonalo. Vipande vingapi vya mkate atabaki navyo?


### Response:
 Pakiti 2 za mkate uliokatwa zina vipande 2 * 20 = <<2*20=40>>40.
Pakiti 2 za jibini lililokatwa zina vipande 2 * 8 = <<2*8=16>>16.
Shane atatengeneza sandwichi 16 kwa sababu ana vipande 16 vya jibini.
Atatumia vipande 32 vya mkate kutengeneza sandwichi hizo kwa sababu 16 x 2 = <<16*2=32>>32.
Atabakiwa na vipande 8 vya mkate kwa sababu 40 - 32 = <<40-32=8>>8.
