Which is not an important determining factor in the value of the american dollar on the currency in international markets?
a: a stable government
b: inflation
c: interest rates
d: the balance of exports/imports
e: its representative value

I believe the answer is: E. Representative value

Representative value does not determine the purchasing power of a currency. It only represent an acknowledgement that we can use a certain object as a medium of exchange. The one that actually determine the purchasing power of a currency is called intrinsic value.
