The ratio of males to females in a class is 2:3. The career preferences of the students in the class are represented in a circle graph. If the area of the graph allocated to each career preference is proportional to the number of students who have that career preference, how many degrees of the circle should be used to represent a career that is preferred by one-half of the males and one-fourth of the females in the class?	Choose one:
A) 120	B) 126	C) 132	D) 138	E) 144
1/2*2/5 + 1/4*3/5 = 4/20 + 3/20 = 7/20   The number of degrees is  7/20 * 360=
