  On Monday Elisa paints 30 square feet of her house's walls. On Tuesday she paints twice that amount. On Wednesday she finishes up by painting half as many square feet as she painted on Monday. How many square feet total does Elisa paint in her house?

conversations.value: On Monday Elisa paints 30 square feet of wall.
  She paints 2 x 30 square feet on Tuesday = 60 square feet of wall.
  On Wednesday Elisa paints 1/2 as many square feet as she painted on Monday, 1/2 x 30 square feet = 15 square feet of wall.
  In total, Elisa paints 30 + 60 + 15 = 105 square feet of wall.
