A mathematics exam-style question with a worked solution that can be revealed gradually
Question id: 409. This question is similar to one that appeared on a GCSE Higher paper in 2017. The use of a calculator is allowed.
46 adults and 52 children visit a bowling alley.
36 of these people have their own bowling shoes.
Five times as many adults as children have their own bowling shoes.
(a) Complete the frequency tree.
(b) The cost of admission to the bowling alley is reduced by 25% if you have your own bowling shoes. If the discounted cost is £8.40, what is the full cost of admission for those who don't have their own bowling shoes?
