To find out how long it will take Stacy to paint the entire room, we need to determine how many parts of the room she can paint in one hour.
If Stacy can paint 34 parts of the bedroom in 3 hours, we can calculate how many parts she can paint in one hour by dividing 34 by 3.
34 parts ÷ 3 hours = 11.33 parts per hour (rounded to two decimal places)
Since Stacy can paint 11.33 parts of the room in one hour, we can conclude that it will take her approximately 11.33 hours to paint the entire room.
However, the answer choices given are in whole numbers, so we need to round the result. Round 11.33 to the nearest whole number.
11.33 rounded to the nearest whole number is 11.
Therefore, it will take Stacy approximately 11 hours to paint the entire room.
Among the given answer choices, the closest one is "12 hours". So the correct answer is "12 hours".
To find out how long it will take Stacy to paint the entire room, we need to determine how much of the room she can paint in one hour.
If Stacy can paint 34 of the bedroom in 3 hours, we can find out how much of the room she can paint in one hour by dividing 34 by 3.
34/3 = 11.3333 (rounded to 4 decimal places)
Therefore, Stacy can paint approximately 11.3333 of the bedroom in one hour.
Since we know that the entire room is 100% and Stacy can paint approximately 11.3333 in one hour, we can divide 100% by 11.3333 to find out how many hours it will take Stacy to paint the entire room.
100/11.3333 = 8.8 (rounded to 1 decimal place)
Therefore, it will take Stacy approximately 8.8 hours to paint the entire room.
So the correct answer is:
8.8 hours
