conversations.value: I need a clearer understanding of how to solve: Daniela goes shopping during a sale. She finds out that the store has 40 percent off on shoes and 20 percent off dresses. If Daniela buys 2 pairs of shoes originally priced at $50 a pair and a dress originally priced at $100, how much money does she spend?

conversations.value: Two pairs of shoes at $50 a pair costs $50 x 2 = $100.
  The shoes are discounted by 40 percent so she only pays 100 - 40 = 60 percent of the original price.
  Therefore the two pairs of shoes cost $100 x 0.60 = $60.
  The dress is discounted by 20 percent so she only pays 100 - 20 = 80 percent of the original price.
  Therefore the dress costs $100 x 0.80 = $80.
  In total Daniela spends $60 + $80 = $140 for two pairs of shoes and a dress.
