conversations.value: First, you need to set up the problem with the information given. The cost of the skirts and art supplies must equal $50.
  Since we know that the cost of the skirts is the same price and that she bought art supplies for $20, we can set up an equation: 2x + 20 = 50, with x being the cost of the skirts.
  To solve the equation, subtract 20 from both sides, to give you the new equation: 2x = 30.
  Solve for x by dividing both sides of the equation by 2, 2x/2 = 30/2 gives you x = 15.
  Therefore, each skirt cost $15.
