Math Problem (9.2.11)

Although you can use US money in some places of business in Grenada, it's always an advantage to have some E.C. (Eastern Caribbean money) where ever you go.  The exchange rate is $1 US to $2.70 E.C.  For Harrison's friends at PDS, can you determine how many E.C. dollars we would receive from the bank if we gave the teller $100 US dollars?
