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

### Instruction:
Amber is baking cakes for her party. She has invited 8 friends and each one will want two slices of cake. Each cake makes 6 slices. If she bakes 4 cakes, how many slices will be left over at the end if she eats three herself?

### Response:
 Amber anahitaji vipande 16 vya keki kwa ajili ya marafiki zake.
Kila keki ina vipande 6, hivyo anahitaji 16 / 6 = <<16/6=2.667>>2.667 keki.
Atahitaji kupika keki 3, na kila keki itakuwa na vipande 6.
Vipande vilivyobaki vitakuwa 6 * 3 - 16 = <<6*3-16=6>>6 vipande.
