conversations.value: Louis is making himself a velvet suit for a formal event. The velvet fabric he chose was $24 per yard. He bought a pattern for $15, and two spools of silver thread for $3 each. If he spent $141 for the pattern, thread, and fabric, how many yards of fabric did he buy?
  Find the solution.

conversations.value: Let V be the number of yards of velvet fabric Louis bought.
  The silver thread cost 2 * 3 = $6.
  He spent 24V + 15 + 6 = $141 on the suit.
  The fabric cost 24V = 141 - 15 - 6 = $120.
  Thus, Louis bought V = 120 / 24 = 5 yards of fabric.
