During the 2011 student's orientation at Unam, it was reported that number of male students who attended the orientation was nine hundred and forty less than four times the number of female students.

Question

a) From the statement above, formulate a mathematical equation expressing the number of male students in terms of female students, given that (f) represent the number of female students and (m) represent the number of male students.
b) Given that the total number of students who were attending this orientation was twenty thousand five hundred and sixty, use the equation you formulated in a) to determine the number of male students who attended the orientation.

Answer 1

a. Females = f.
Males = 4F - 940,
m = 4f - 940.

b. f + (4f-940) = 20560,
5f - 940 = 20560,
5f = 20560 + 940 = 21500,
f = 4300 Female students,

m = 4*4300 - 940 = 16260 Male students.
