Well, I am not going to ask you to solve nor to discuss the solution of the problem beside.
The question was taken from the ‘Examen Vwo‘ of Wiskunde B, a yearly math event in the Netherlands.
What I am going to show you from the picture is related to the title of this post, “Does context only match with lower level math?” which is rather be a common question, at least, by several Indonesian teachers. Furthermore, some of them used it as an excuse for not applying RME, CTL, or involve any context in their teaching of higher level math. As the consequence, most of our students feel less motivated in learning math since they did not find it useful for them.
