conversations.value: While at Wizards Park, Kate buys 3 magic wands, one for herself and two for her friends. When she returns she sells the wands to her friends for $5 more than she paid. If she collected $130 after the sale, how much money did each wand cost?
  Solve it.

conversations.value: Out of 3 wands purchased, Kate sold her friends 3 wands - 1 wand = 2 wands.
  For 2 wands she charged $130, so for 1 wand she charged $130 / 2 wands = $65/wand.
  Since she charged $5 more for each wand than she paid, Kate paid $65 - $5 = $60 for each wand.
