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

### Instruction:
Rebecca bought 2 pies for the holiday weekend.  Each pie was sliced into 8 slices.  Rebecca ate 1 slice of each pie.  Her family and friends ate 50% of the remaining pies over the weekend.  On Sunday evening Rebecca and her husband each had another slice of pie.  How many slices are remaining?

### Response:
 Pai 2, kila moja na vipande 8, ni jumla ya vipande 2*8 = <<2*8=16>>16.
Rebecca alikula kipande 1 cha kila pai, hivyo vipande vilivyosalia ni 16 - 2 = <<16-2=14>>14.
Familia na marafiki walikula 50% ya pai, ambayo ni vipande 14 / 2 = <<14/2=7>>7.
Kabla ya vitafunio vya Rebecca na mumewe, kulikuwa na vipande 14 - 7 = <<14-7=7>>7 vilivyosalia.
Baada ya vitafunio, kulikuwa na vipande 7 - 2 = <<7-2=5>>5 vilivyosalia.
