Answer:
Amelia used a total of 20 + 3 = 23 pints of paint to paint her bedroom.
Explanation:
First, we need to convert 2 1/2 gallons to pints.
1 gallon = 8 pints
So, 2 1/2 gallons can be written as:
2 × 8 + 1/2 × 8 = 16 + 4 = 20 pints
Therefore, Amelia used a total of 20 + 3 = 23 pints of paint to paint her bedroom.
