To convert Saudi Riyals (SAR) to US Dollars (USD), you'll need the current exchange rate. As of my last knowledge update, the exchange rate was approximately 1 SAR = 0.27 USD. However, exchange rates fluctuate regularly.
Using that approximate rate:
350 SAR * 0.27 USD/SAR ≈ 94.5 USD
Please check a reliable financial news source or currency converter for the most current rate.
