One hundred people were surveyed about their favorite kind of yogurt. how many more people prefer chocolate than vanilla?
(vanilla- 25%)
(swirl-35%)
(chocolate- 40%)
a. 10
b. 15
c. 25
d. 40

b) 15

Step-by-step explanation:

Given that,

Total people = 100

% of people prefer vanilla = 25%

Number of people prefer vanilla out of 100 = 25% of 100

=> 25/100 * 100 = 25

% of people prefer swirl = 35%

Number of people prefer swirl out of 100 = 35% of 100

=> 35/100 * 100 = 35

% of people prefer chocolate = 40%

Number of people prefer chocolate out of 100 = 40% of 100

=> 40/100 * 100 = 40

The number of more people preferring chocolate over vanilla =  40 - 25

=> 15 so option b is correct

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5
