Answer:
A: 3 Quarts
Step-by-step explanation:
1 gallon = 4 quarts
1/4 of 2 gallons = 1/4 × 2
= 1/2 gallon
⇒ 1/2 gallon = 2 quarts
Therefore, Mieko used 2 quarts of paint to paint her bedroom.
If she used 3 quarts to paint the hallway, then
⇒ total number of quarts used = 2 + 3 = 5 quarts
As she bought a total of 2 gallons of paint:
⇒ 2 gallons = 2 × 4 = 8 quarts
Therefore the remaining unused paint (to paint the living room) is:
⇒ total paint - used paid = 8 quarts - 5 quarts
= 3 quarts
