Answer:
20 sodas
Explanation:
In order to calculate the number of regular sodas sold, we can use the following equation:
Number of regular sodas = 40% of 50 sodas
Number of regular sodas = 0.40 Ă— 50 sodas
Number of regular sodas = 20 sodas
Therefore, Braden's Diner served 20 regular sodas last night.
