Let's denote the number of glasses of plain lemonade sold as P and the number of glasses of strawberry lemonade sold as S.

From the information given, we know that Anna made $16 from selling strawberry lemonade. We also know that she made $11 more from plain lemonade than strawberry lemonade. Therefore, the total amount made from plain lemonade is $16 + $11 = $27.

Since each glass of plain lemonade was sold for $0.75, we can set up the following equation to find the number of glasses of plain lemonade sold:

0.75 * P = $27

Now, we solve for P:

P = $27 / 0.75
P = 36

Therefore, Anna sold 36 glasses of plain lemonade.
