Lesson $17: Unit Conversions
Currency conversion rates fluctuate (change) over time as trade and tourism
cause people to demand more or less of a given type of money relative to
others. The table to the right was taken from the NY Times on 10/3/2010 at
9 PM. It tells you the current cost in US dollars for a variety of currencies in
North, Central, and South America and the Caribbean.
Use the factor-label method to solve the following. Show the full setup
with unit cancellations. You may use a scientific calculator to perform
calculations, but you must show your setup.
