The school received 14 rolls of free movie tickets from a local theater. There are 48 tickets in each roll. The school has 32 classes of 24 students each. If the school plans to give one ticket to each student, which of the following statements is true?
A. The school will have 40 tickets left over.
B. The school will have exactly enough tickets.
C. The school will need 2 more rolls of tickets.
D. The school will need 4 more rolls of tickets.

14 * 48 = 672
32 * 24 = 768
768  672 = 96 
which statement is true and how?

The school needs 96 more tickets.
That makes either C or D true. Which is it? 
C is the correct answer because there are 96 more students than there are tickets.
