Question

Mr and mrs Lim took their 2 children to the bird park.An adult ticket cost 4 times as much as a child’s ticket.Mr Lim paid a total of $120 for all tickets.What was the cost of a child’s ticket?

Answer 1

I believe a child ticket costs $12 and adult tickets costs $48.

First, you have to get those $12 times the 2 children which is $24. If you do $48 times 2 for the two parents, it is $96. Once you add all the tickets together, you get $120.

Answer 2

c = unknown

a = 4c

120 = 2a + 2c

120 = 2(4c) + 2c

120 = 8c + 2c

120 = 10c

120/10 = 10c/10

c = 12
