Answer:20
The circle graph shows the results of a survey that out of 80 only 20 people ride the bike to get to the city park.
Hence Option B . 20 is the correct answer.
80 people were asked that which method of transportation they use to get to the city park.
We have to determine that how many people ride bike to the city park
According to the circle given
Total number of people asked for the method of transportation = 80
Percentage of people using bus as a transportation mode = 40%
Percentage of people using walk as transportation mode = 10%
Percentage of people using bike as transportation mode = 25%
Percentage of people using car as transportation mode = 25%
Let x be the number of people riding the bike hence from the circle we can say that
25% of 80 = x
