How many positive integers less than 200 are there such that they are multiples of 13 or multiples of 14?	Choose the most appropriate option
A) 25  B) 26  C) 27  D) 28  E) 29
200/13 = 15 (plus remainder) so there are 15 multiples of 13   200/14 = 14 (plus remainder) so there are 14 multiples of 14   We need to subtract 1 because 13*14 is a multiple of both so it was counted twice.   The total is  15+14-1=
