How much is $500 US in Paraguay?

Could you please clarify the current exchange rate for me? I'm trying to understand how much Paraguayan Guarani would $500 US dollars be equivalent to? Is there a specific way I can calculate this, or is there a service you recommend I use to get the most accurate figure? It's important for me to know the exact amount for a financial transaction I'm planning, so any information you can provide would be greatly appreciated.
