conversations.value: I need a clearer understanding of how to solve: Ella earned $33 for 3 hours of dog walking. If she continues to walk dogs at the same rate, how much would she earn after 12 hours?

conversations.value: Ella earned $33 / 3 hours of dog walking = $11 per hour.
  So for 12 hours of dog walking, Ella would earn $11 x 12 = $132.
