Answer:
The implied French franc/US dollar exchange rate will be - FF19.84/$
or
$0.0504/FF
Explanation:
Assuming the price of an ounce of gold in US dollars ($/oz) $20.67
Assuming the price of an ounce of gold in French francs (FF/oz) 410.00
The implied French franc/US dollar exchange rate will be :
FF410/$20=FF19.84/$ ( FF19.84 is equal to one dollar)
Alternatively, this can be expressed as follow :
$0.0504/FF (i.e $0.0504 is equal to one FF - 1/19.84)
