Question

Mr and Mrs Boyden take their 3 children to a leisure park.
They buy tickets for the whole family.
The cost of an adult ticket is £6 more than the cost of a child ticket.
The total cost of the 5 tickets is £82.

Work out the cost of an adult ticket.

Answer 1

ac = cc + 6 so cc = ac - 6
2 ac + 3 cc = 82
=============
2 ac + 3 (ac-6) = 82
2 ac + 3 ac - 18 = 82
5 ac = 100

Answer 2

the cost of an adult ticket = 20 if you just want the answer
