prompt: A pastry chef is making brownies but is running out of butter.  The recipe he is following calls for 2 ounces of butter for every 1 cup of baking mix; however, it allows 2 ounces of coconut oil to be substituted for the 2 ounces of butter if necessary.  The chef would like to use as much butter as possible before switching over and substituting coconut oil.  If the chef had 4 ounces of butter remaining, and he plans on using 6 cups of baking mix, how many ounces of coconut oil will he end up using?

messages.content: Every 2 ounces of butter is enough to cover 1 cup of baking mix, so the chef's remaining 4 ounces of butter will be enough to cover 4/2 = <<4/2=2>>2 cups of baking mix.
  This leaves 6 - 2 = <<6-2=4>>4 cups of baking mix that will require the use of coconut oil as a substitute.
  Since each cup of baking mix requires 2 ounces of coconut oil, these 4 cups will require a total of 4*2 = <<4*2=8>>8 ounces of coconut oil.
