3. the matrices show the enrollment of boys and girls on the basketball, lacrosse, and soccer teams in two towns

(a) if we let matrix a be the matrix for town a, what is the element , and what does it represent?
(b) if we let matrix b be the matrix for town b, what is the address of the element that represents the number of girls enrolled in basketball in town b?
(c) what is the matrix that results when you subtract matrix a from matrix b?
(d) name the matrix you found in part (c) matrix c. what is element , and what information does it tell you about the number of girls enrolled in lacrosse in town b compared with town a?
(e) what is the matrix that shows the enrollment in town a after a 12.5% increase in enrollment in all sports and in both genders? (hint: find 1.125a.)
