The price of a dozen roses in the united states is $30. if $0.3472 can purchase 1.00 turkish lira, how much does the same dozen roses cost in turkey if purchasing power parity holds

For this case we can make the following rule of three:
 0.3472 $ > 1.00 turkish lira
 $ 30 > x
 Clearing x we have:
 x = (30 / 0.3472) * (1)
 x = 86.40552995 turkish lira
 
 the same dozen roses costs:
 x = 86.40552995 turkish lira
