30 points 3. For her eighth birthday, Shelley's grandmother gave her a full bag of
candy. Shelley counted her candy and found out that there were 160
pieces in the bag. As you might suspect, Shelley loves candy, so she ate
half the candy on the first day. She will continue to eat half of the candy
that is left in the bag each day. She thinks that this way she can eat candy
every day and never run out. Which function models the total amount of
candy, c, after d days?
