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 tot al of $120 for all tickets.What was the cost of a child’s ticket?
2 answers:
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.
c = unknown
a = 4c
120 = 2a + 2c
120 = 2(4c) + 2c
120 = 8c + 2c
120 = 10c
120/10 = 10c/10
c = 12
