conversations.value: Provide a step by step solution for the following math problem: Faye had $20. Today, her mother gave her twice as much as her money. If she bought ten cupcakes at $1.50 each and five boxes of cookies at $3 per box, how much money did she have left?

conversations.value: Faye's mother gave her 2 x $20 = $40.
  So, Faye had a total of $20 + $40 = $60.
  Ten cupcakes cost 10 x $1.50 = $15.
  Five boxes of cookies cost 5 x $3 = $15.
  Thus, Faye spent $15 + $15 = $30.
  Therefore, Faye has $60 - $30 = $30 left.
