Calculating percentage and converting? Too long, so I put it in the description :)

Jenna sells Lemonade for $10 per glass. She offers a 20% discount. The price is recalculated then she offers an additional 10% discount. Aidan wants to match her deal by offering a single discount percentage . What should his discount percentage be?

Thanks so much!

Students have a lot of problem over the percentage.  The best way is use algebra
 If a merchandise price reduced by 20% , means it sells for 80% of original price.
   Write down an algebraic expression for 80% of the original price.
  .80 P , then let this equal to discounted price and solve it.
