Perhaps we mix units here for the same reason we mix units in length,
such as 5'4" rather than 5 1/3 ft or 5.333333... ft, it takes training
to know that 4" and 1/3 ft are the same. In monitary (sp?) terms, we
have coinage for parts of a whole dollar and we call them cents.

In the supermarket, I cannot tell you the number of times that I have
seen items marked as .49 cents. I am tempted to try to purchase 100
units and pay the $.49 it SHOULD cost. Another worry is the number of
students (not only those in developmental courses) who write $.49 as
cents 49 (using the cent symbol) or worse cents .49.
