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

### Instruction:
Oleg is an event organizer. He is organizing an event with 80 guests where 40 of them are men, half the number of men are women, and the rest are children. If he added 10 children to the guest list, how many children will there be at the event?

### Response:
 Kuna wanawake 40/2 = <<40/2=20>>20 kwenye tukio hilo.
Hivyo, jumla ya wanaume na wanawake kwenye tukio hilo ni 40 + 20 = <<40+20=60>>60.
Hivyo, kuna watoto 80 - 60 = <<80-60=20>>20.
Baada ya Oleg kuongeza watoto 10 kwenye orodha ya wageni, kuna watoto 20 + 10 = <<30=30>>30 kwenye tukio hilo.
