12 u |
12 u |
24 u |
Price of 1 child ticket = 2 u
Price of 6 child tickets = 6 x 2 u = 12 u
Price of 1 adult ticket = 3 u
Price of 4 adult tickets = 4 x 3 u = 12 u
Total cost of the tickets
= 12 u + 12 u
= 24 u
24 u = 144
1 u = 144 ÷ 24 = 6
Price of an adult ticket
= 3 u
= 3 x 6
= $18
Answer(s): $18
