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.

1) Jorge, a hip 20-something from Chile, is hoping to buy some Levi’s
and Converse sneakers on his big trip to NYC. The total bill comes to
\$378. How many Chilean Pesos is this going to cost him?

2) Polly, an adventuresome American, is hiring a local guide to help her
visit the absolutely amazing ruins of Machu Pichu, in Peru. He asks
for 150 NEW SOL for a two day trek. How many US dollars is this?

3) Juan-Carlos is a Brazilian police officer who works at the airport. American smugglers offer him a bribe of \$50
to get some illegal gummy bears into the country. How many Brazialian REAL is this bribe worth?

4) Argentinian beef is considered some of the best in the world. If free-range Argentine Filet Mignon costs 40
PESOS per pound, how many dollars per pound does it cost?

5) If Kimberly s mom is sending her grandmother \$40 US this month, how many Dominican PESO is this?
