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

### Instruction:
A waterpark opens up and charges $30 for admission.  Kids' tickets are half price.  If a group of people brings a soda, they can get 20% off the total price of admission.  Janet gets tickets for 10 people and 4 of them are children.  She buys a soda for $5 to take advantage of the discount for her group.  How much did she pay for everything?

### Response:
 Alinunua tiketi za watu wazima 10-4=<<10-4=6>>6
Kwa hivyo 6*30=$<<6*30=180>>180 ndio gharama ya tiketi za watu wazima
Tiketi za watoto zinagharimu 30/2=$<<30/2=15>>15 kila moja
Kwa hivyo tiketi za watoto zinagharimu 15*4=$<<15*4=60>>60
Kwa hivyo jumla ya gharama ni 180+60=$<<180+60=240>>240
Wanapata punguzo la 240*.2=$<<240*.2=48>>48
Hii inamaanisha alilipia 240-48=$<<240-48=192>>192
Kwa hivyo jumla ya gharama ni 192+5=$<<192+5=197>>197
