conversations.value: Find the answer to this math problem: GiGi took out a big bowl of mushrooms from the refrigerator.  She cut each mushroom into 4 pieces.  Her twins, Kenny and Karla sprinkled mushrooms on their pizzas and baked them in the oven.  Kenny grabbed a handful and sprinkled 38 mushroom pieces on his pizza.  Karla scooped them up with both hands and sprinkled 42 mushroom pieces on her pizza.  On the cutting board, were 8 pieces of mushrooms remaining.  How many mushrooms did GiGi cut up at the beginning?
conversations.from: assistant
conversations.value: Kenny used 38 / 4 = 9.5 mushrooms on his pizza.
  Karla used 42 / 4 = 10.5 mushrooms on her pizza.
  Together, the twins used 9.5 + 10.5 = 20 mushrooms.
  There are 8 / 4 = 2 mushrooms left on the cutting board.
  GiGi cut up 20 + 2 = 22 mushrooms at the beginning.
