Step-by-step explanation
Part A) The information of the table amounts to the information of
students. Since Jake surveyed 25 students, the remaining 7 students are those who live about 2 miles from school.
Part B) This part is a little "linguistic". To say "the students living about 2 miles or less from school" is the same as to say "the students living about 2 or 1 miles from school". Looking at the table, we note that there are
of such students. How many more students live about 2 or less miles from school than students who live about 3 miles from school? Well, this number is the difference between the numbers of those groups: Looking at the table again, we note that there are
students that live about 3 miles from school. Then, there are
more students living about 2 miles or less from school than students who live about 3 miles from school.
Answer
Part A) There are 7 students living about 2 miles from school.
Part B) There are 15 more students living about 2 miles or less from school than students who live about 3 miles from school.
