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

### Instruction:
Out of the 200 cookies that Javier baked from the recipe he learned online, his wife took 30%, and his daughter took 40 from the remaining cookies. If he ate half of the remaining cookies, how many cookies did they not eat?

### Response:
 Kati ya biskuti 200, mkewe Javier alikula 30/100*200 = <<30/100*200=60>>60
Baada ya mkewe kula biskuti 60, idadi ya biskuti zilizosalia ilikuwa 200-60 = <<200-60=140>>140
Binti yake pia alikula biskuti 40, zikisalia 140-40 = <<140-40=100>>100.
Ikiwa Javier alikula nusu ya biskuti zilizosalia, alikula 1/2*100 = 50.
Ikiwa alikula nusu ya biskuti zilizosalia, idadi ya biskuti ambazo hawakula ni 100-50 =50
