Prime numbers are numbers that have factors which are only 1 and itself.
So, for the sum of 3 prime number to equal 12; those prime numbers would have to be the following:
3
7
2
7 + 3 = 10
10 + 2 = 12
Yes. 2 is actually a prime number. It's only factors are 1 and itself. Which does contradict popular belief as most people think all even numbers are not prime.

Answer:
child tickets: 115
adult tickets: 175
Step-by-step explanation:
number of child tickets = x
number of adult tickets = y
(value of child ticket [8] * number of child tickets [x]) + (value of adult ticket [8.5] * number of adult ticket [y]) = total value (2407.50)
8x + 8.5y= 2407.50
290 (total number of tickets) = x (number of child tickets) + y (number of adult tickets)
290 = x+y
system of equations: 8x + 8.5y= 2407.50
290 = x + y
solve equation:
x = 115
y = 175
8c = 14 - 5c - 1
13c = 13
c = 1
