question: Two cups of flour are needed to make a dozen cookies. Carla is making 36 cookies today and 30 cookies tomorrow. How many cups of flour will Carla need to bake the cookies today and tomorrow?
answer: Carla will bake a total of 36 + 30 = <<36+30=66>>66 cookies.
  Since 1 dozen is equal to 12, then 66 cookies are equal to 66/12 = <<66/12=5.5>>5.5 dozens.
  Hence, Carla will need 5.5 x 2 = <<5.5*2=11>>11 cups of flour.
