Answer:
Adult tickets = 18
Children tickets = 25
Step-by-step explanation:
We can write 2 equations and solve:
let number of adult tickets be a and number of children tickets be c
Adult ticket cost is 8 and children cost is 5 and total money is 269, thus:
1. 8a + 5c = 269
Also, he sells seven more children's tickets than adult tickets, thus:
2. c - 7 = a
Now substituting 2 into 1, we can solve for c:
8a + 5c = 269
8(c-7) + 5c = 269
8c - 56 + 5c = 269
13c = 325
c = 325/13 = 25
Now using equation 2, we can solve for a:
c - 7 = a
25 - 7 = a
a = 18
So, 18 adult tickets and 25 children's ticket

100+160/500 consist of only vegetarians, or only non-vegetarians, which equal 260/500=13/25 probability. ☺☺☺☺
Im pretty sure the value of x in this equation is -3 because -3 plus 5 would equal 2.
