conversations.value: Can you explain how to solve this math problem: Karl sells clothing in his store. He sells a T-shirt that costs $5, some pants that cost $4, and some skirts that cost $6, he also sells some refurbished t-shirts that cost half the original price. How much is his total income if he sold two T-shirts, one pair of pants, four skirts, and six refurbished T-shirts?

conversations.value: The refurbished T-shirt costs $5 / 2 = $2.5.
  He earn $2.5 x 6 = $15 for the refurbished T-shirt.
  He can earn $5 x 2 = $10 for the T-shirts.
  He can earn $4 x 1 = $4 for the pants.
  He can earn $6 x 4 = $24 for the skirts.
  Therefore Karl can earn a total of $15 + $10 + $4 + $24 = $53.
