conversations.value: I'm completely lost with this math problem: A pound of almonds costs $10 while a pound of walnuts costs $15. How much more does it cost for a mixture of 1/2 pound almonds and 1/3 pound walnuts than a mixture of 1/5 pound almonds and 1/3 pound walnuts?
  Can you give me a hand?

conversations.value: One-half pound of almonds cost $10/2 = $5.
  One-fifth pound of almonds cost $10/5 = $2.
  A one-third pound of walnuts costs $15/3 = $5.
  So, 1/2 pound almonds and 1/3 pound walnuts cost $5 + $5 = $10.
  And 1/5 pound almonds and 1/3 pound walnuts cost $2 + $5 = $7.
  Therefore, 1/2 pound almonds and 1/3 pound walnuts cost $10 - $7 = $3 more than a mixture of 1/5 pound almonds and 1/3 pound walnuts.
