I am studying for an exam in marketing, and there's the following sample question:
The main reasons that people choose products in category X is: 1. Brand 2. Price. Where the importance ranking is 50% Brand and 50% Price. Brand A’s utility is 50 and Brand B’s utility is 30. What is the maximal pricing among the following of Brand B’s product so that it will be preferred by the market if the pricing of A is $80?
The correct answer is (b). How do they get to this number? My only idea of how to solve this would be to multiply $80 by 30/50 but that's not even an option. Thank you.
