The Amazing Aloysius is practicing one of his tricks. As part of this trick, he cuts a rope into many pieces and then magically puts the pieces of rope back together. He begins the trick with a 20-foot rope and then cuts it in half. He then takes one of the halves and cuts that piece in half. He repeats this process until he is left with a piece so small he can no longer cut it.

The number of guests at a ski resort on any given day is related to the day’s high temperature. If the high temperature is –20°F or below, no one comes

to the resort. As the temperature increases, so does the number of guests. Once the temperature reaches 0°F and increases through the single digits, the number of guests soars. If the temperature is 10°F or higher, the ski

resort is at full capacity with 400 guests.
