Lucy and Jack are training for a marathon. Lucy started the first day by running 2 miles and adds 0.25 miles to her distance every day. Jack started the first day by running 0.5 miles and adds 0.5 miles to his distance every day. If both continue this plan, on what day will Lucy and Jack run the same distance?

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
