3 u |
4 u |

Total value |
9 u |
28 u |
37 u |
Price of 1 child ticket = 3 u
Price of 3 child tickets = 3 x 3 u = 9 u
Price of 1 adult ticket = 4 u
Price of 7 adult tickets = 7 x 4 u = 28 u
Total cost of the tickets
= 9 u + 28 u
= 37 u
37 u = 185
1 u = 185 ÷ 37 = 5
Price of a child ticket
= 3 u
= 3 x 5
= $15
Answer(s): $15
