How many positive integers less than 250 are there such that they are multiples of 15 or multiples of 16?	Pick:
A) 28.  B) 29.  C) 30.  D) 31.  E) 32.
250/15 = 16 (plus remainder) so there are 16 multiples of 15   250/16 = 15 (plus remainder) so there are 15 multiples of 16   We need to subtract 1 because 15*16 is a multiple of both so it was counted twice.   The total is  16+15-1=
