If Stacy is able to paint 3/4 of the room in 3 hours, we can set up a proportion to find out how long it will take her to paint the entire room.
3/4 of the room takes 3 hours
1/4 of the room will take 3/4 * 1/3 = 1/4 * 1/3 = 1/12 of the time
So, it will take Stacy 1/12 * 12 = 1 hour to paint 1/4 of the room.
Therefore, it will take Stacy a total of 3 + 1 = 4 hours to paint the entire room.
The correct answer is 4hr.
