The answer is A, 651. You would first start by multiplying the number of students, 1,860, by 45%, or .45. You'd come out with the answer of 837. You would then add 837 and 372 together to get a sum of 1,209. Finally, you would subtract 1,209 from the total number of students, which was 1,860 and get an answer of 651.
