2 u |
7 u |

| Total value |
8 u |
28 u |
36 u |
Price of 1 child ticket = 2 u
Price of 4 child tickets = 4 x 2 u = 8 u
Price of 1 adult ticket = 7 u
Price of 4 adult tickets = 4 x 7 u = 28 u
Total cost of the tickets
= 8 u + 28 u
= 36 u
36 u = 144
1 u = 144 ÷ 36 = 4
Price of a child ticket
= 2 u
= 2 x 4
= $8
Answer(s): $8
