Suggestion: Using purchasing power parity, adjust the exchange rate to compensate for inflation. That is, determine the relative rate of inflation between the United States and Saudi Arabia and multiply this times $ per riyal of 0.46 . What should the exchange rate be in 2008 ? Note: Do not round intermedlate calculations. Round your answer to 2 decimal places
