Okay the question is
A college surveyed 3500 of its student to determine if the students preffered music, movies, or sports. The results of the survey are shown in the relative frequency table below..

MUSIC Movies Sports
Freshman 0.06 0.10 .09
Sophomores 0.09 0.05 .10
Juniors 0.10 0.06 .08
Seniors 0.8 0.09 .10

How many more seniors than juniors were included?? Explanation would be awesome

I'm going to guess that the first number in the "Seniors" row is meant to be "0.08". If so, then all the values sum to 1 (for "100% of the people asked").

You are given percentages who had various preferences. Try multiplying those percentages by the total, to get the absolute numbers. Then subtract to find the difference. ;)
