Answer: 1,069.5
Step-by-step explanation: First you want to find the number of adults. We know that 2/3 of the 345 people are adults. 2/3 x 345 is 230 adults. If you subtract 345 from 230, you get 115 kids.
To find the cost of the tickets, we know that the kid's tickets cost 2/3 the number of adults tickets (13.95). 2/3 x 13.95 is $9.3.
If there's 115 kids and each ticket costs $9.3, 115 x 9.3 is $1,069.50.
