As of January 2013, the U.S. Postal
Service charged $0.46 postage
for first-class letters weighing up
to and including 1 ounce, plus a
flat fee of $0.20 for each
additional or partial ounce up to
and including 3.5 ounces.
First-class letter rates do not
apply to letters weighing more
than 3.5 ounces.

Notice 123.
Find a function C that models the first-class postage charged, in dollars, for a letter weighing w ounces. Assume w > 0.
Note: The answer in the back of the textbook is a huge piecewise function. The only thing I understand here is that w is positive. Can someone break this problem down piece by piece to create a piecewise function? I cannot make the needed connection between the words here that would lead to a piecewise function.
