15 u |
24 u |
39 u |
Price of 1 child ticket = 5 u
Price of 3 child tickets = 3 x 5 u = 15 u
Price of 1 adult ticket = 6 u
Price of 4 adult tickets = 4 x 6 u = 24 u
Total cost of the tickets
= 15 u + 24 u
= 39 u
39 u = 156
1 u = 156 ÷ 39 = 4
Price of a child ticket
= 5 u
= 5 x 4
= $20
Answer(s): $20
