conversations.value: I'm completely lost with this math problem: Alan likes to support music creators, so instead of downloading songs from the internet, he visits a record store once in a while. He decided now to buy 2 CDs by "The Dark", 1 CD by the creator "AVN", and 5 CDs that are mixes of songs from the 90s. The price of the "AVN" CD is $12 and it is half the price of one CD by "The Dark". The 5 CDs of 90s music cost is 40% of all the cost of all other CDs Alan is going to buy. How much will Alan have to pay for all the products?
  Can you give me a hand?

conversations.value: If one "AVN" is half the price of one "The Dark" CD, that means one CD of "The Dark" costs 12 * 2 = $24.
  So for two "The Dark" CDs, Alan needs to pay 24 * 2 = $48.
  So all CDs cost by now 12 + 48 = $60.
  The 90s music CDs cost 40/100 * 60 = $24.
  That means for all CDs Alan needs to pay 60 + 24 = $84.
