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

### Instruction:
Janette went camping for 5 days. She brought along 40 pieces of beef jerky. She wants to ration it out so that she can eat 1 for breakfast, 1 for lunch, and 2 for dinner each day. When she returns from the trip, she plans on giving half of the remaining pieces to her brother. How many pieces of beef jerky will she have left once she does this?

### Response:
 Kila siku anatumia jumla ya vipande 4 ya nyama ya jerky.
Safari ni ya siku 5, hivyo atatumia jumla ya vipande 4 * 5 = <<4*5=20>>20 vya nyama ya jerky.
Atampa nduguye nusu, ambayo itamwachia jumla ya vipande 20 / 2 = <<20/2=10>>10 vya nyama ya jerky.
