2 u |
3 u |
|
Total value |
16 u |
12 u |
28 u |
Price of 1 child ticket = 2 u
Price of 8 child tickets = 8 x 2 u = 16 u
Price of 1 adult ticket = 3 u
Price of 4 adult tickets = 4 x 3 u = 12 u
Total cost of the tickets
= 16 u + 12 u
= 28 u
28 u = 168
1 u = 168 ÷ 28 = 6
Price of an adult ticket
= 3 u
= 3 x 6
= $18
Answer(s): $18
