Anna sold 36 glasses of plain lemonade for $0.75 each. If she made $16 total from selling strawberry lemonade, how much more did she make from plain lemonade than strawberry?
First find Anna's total earnings from the plain lemonade: 36 glasses * $0.75/glass = $<<36*0.75=27>>27
Then subtract her earnings from the strawberry lemonade to find the difference: $27 - $16 = $<<27-16=11>>11
