Use reasoning to answer the following question.
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?

197
She bought 10 - 4 = 6 adult tickets.

So 6 * 30 = $180 was the cost for adult tickets.

Children tickets cost 30 / 2 = $15 each.

So the children tickets cost 15 * 4 = $60.

So the total cost of tickets is 60 + 180 = $240.

They get a 240 *.

2 = $48 discount.

So the tickets cost 240 - 48 = $192.

So in total she paid 192 + 5 = $197.

.

The final answer: 197
