Answer:
The Answer is: Adult Tickets: 604 ; Student Tickets: 502 ; Children Tickets: 251.
Step-by-step explanation:
8a + 6s + 5c = $9,099
Let s = students. Let adult = s + 102. Let children = s/2
Substitute and solve for s (Number of Student Tickets):
8(s + 102) + 6s + 5(s/2) = 9099
8s + 816 + 6s + 5s/2 = 9099
14s + 5s/2 = 9099 - 816
14s + 5s/2 = 8283
28s + 5s = 16566
33s = 16566
s = 502
, so there are 502 student tickets.
Add 102 to get the number of Adult tickets: 604.
Divide by 2 to get the number of children tickets: 251.
Proof:
8(502 + 102) + 6(502) + 5(251) =
8(604) + 6(502) + 5(251) =
$4,832 + $3,012 + $1,255 = $9,099

If there is an even number of numbers locate the two middle numbers so that there is an equal number of values to the left and to the right of these two numbers. Step 3: If there is an odd number of numbers, this middle number is the median. If there is an even number of numbers add the two middles and divide by 2.
