Final answer:

Anna used a scale factor of 1/48 for her scale drawing of the game room, meaning one inch on the drawing represents 48 inches, or 4 feet, in real life.

Step-by-step explanation:

Anna used a scale for her drawing where 2 inches represent 8 feet in real life. To find the scale factor that Anna used, we can set up a ratio that compares the drawing length to the real-life length. We do this by dividing the length on the drawing by the corresponding length in real life:

Scale factor = length on drawing / real-life length

Scale factor = 2 inches / 8 feet

To convert feet to inches (since there are 12 inches in a foot), we multiply the real-life length by 12:

Scale factor = 2 inches / (8 feet × 12 inches/foot)

Scale factor = 2 inches / 96 inches

Scale factor = 1/48

Therefore, the scale factor that Anna used for her scale drawing of the pool table is 1/48. This means that one inch in the drawing represents 48 inches, or 4 feet, in real life.
