Final answer:
The distance of the carnival fair ring toss was increased from 8 feet to 10 feet, resulting in a 25% increase. This was calculated by finding the difference in distance, comparing it to the original distance, and converting it to percent.
Step-by-step explanation:
To find the percent of change when the distance of the carnival fair ring toss was moved from 8 feet to 10 feet, we first calculate the difference in distance:
New distance - Original distance = 10 feet - 8 feet = 2 feet
Next, we divide the difference in distance by the original distance to find the proportional change:
2 feet / 8 feet = 0.25
Finally, to express this as a percent, we multiply by 100:
0.25 × 100 = 25%
The distance from the target increased, so this is a 25% increase.
Therefore, the answer to the question is a) 25% increase.
