Eggs regularly cost $20 ARS each. Mommy bought six. But they're on sale now, three for the price of two. So, how much did she pay?

**A Little Harder**

Mommy gave the lady $100 ARS, but was told she needed four more pesos. Mommy's hearing is going -- turns out the original price

*wasn't*$20 per egg... how much was it?

**If You REALLY Want a Challenge**

How much does one egg cost (both regular and discounted price) in USD if the blue rate today is 10.3? 9.6? 12.2? Hehe.
