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

### Instruction:
Flies are Betty's frog's favorite food. Every day the frog eats 2 flies. Betty puts the flies she finds in a bottle. In the morning Betty catches 5 flies inside a bottle, and in the afternoon she catches 6 more, but when she removes the lid, one escapes.  Betty wants to gather the whole week's food for her frog. How many more flies does she need?

### Response:
 Chura hula nzi 2 kwa siku * 7 siku kwa wiki = <<2*7=14>>14 nzi kwa wiki.
Betty hukamata nzi asubuhi na mchana, jumla ya nzi 5 + 6 = <<5+6=11>>11.
Lakini 1 nzi hutoroka, kubaki nzi 11 - 1 = <<11-1=10>>10.
Ili kupata chakula cha wiki nzima kwa chura wake, Betty anahitaji nzi 14 - 10 = <<14-10=4>>4 zaidi.
