charissa bought several packages of pencils from the collage bookstore. if each package contained either 5 or 12 pencils which of the following could not be the total number of oencils she bought?
A) 32
B ) 33
C ) 34
D ) 35
E ) 36
eliminate any answer that’s a multiple of 5 or 12, so choices d and e are out.
32 - 12 = 20, which is a multiple of 5. It’s out. 34 - 24 = 10, which is a multiple of 5, so it’s out.28 is the answer.

28 is not an option. B is the answer. Just make the sum.
5+5+12+12=34
5+5+5+5+12=32
5+5+5+5+5+5+5=35
12+12+12=36
