In the morning, Ms. Wilkins put some pencils for her students in a pencil box. After a while, she found that ½ of the pencils were gone. A little later, she found that of the pencils that were left from when she checked before ⅓ were gone. Still later, Ms. Wilkins found that ¼ of the pencils that were left from the last time she checked were gone. At that point there were 15 pencils left. No pencils were ever added to the pencil box.

Ambrosia weighed her bag and found that there were a grams of candy in total. Ambrosia ate half her candy on the first day (the day after Halloween). Her father told her that if she continued to eat it at that rate the candy would only last one more day, so Ambrosia decided that each day she would only eat half of the weight of the candy left in the bag. She hypothesised that this would allow her to eat candy every day and never run out. Ambrosia decided it might be useful to use Mathematics to think about her remaining candy. She assigns t and W such that • t is a variable representing the number of days since Halloween. • W(t) represents the weight (in grams) of the remaining candy at the end of the day t. To understand what would be an appropriate mathematical model for this problem Ambrosia…
