3 u |
10 u |
13 u |
Price of 1 child ticket = 1 u
Price of 3 child tickets = 3 x 1 u = 3 u
Price of 1 adult ticket = 2 u
Price of 5 adult tickets = 5 x 2 u = 10 u
Total cost of the tickets
= 3 u + 10 u
= 13 u
13 u = 143
1 u = 143 ÷ 13 = 11
Price of an adult ticket
= 2 u
= 2 x 11
= $22
Answer(s): $22
