Of the 420 members at a health club, 260 use the weight room and 300 use the pool. If at least 60 of the members do not use either, then the number of members using both the weight room and the pool must be between:	Choose the correct choice:
A) 200 to 260  B) 160 to 260  C) 220 to 260  D) 220 to 300  E) 40 to 100
W=260   P=300   200 to 260LL=420   N(NEITHER)=200 to 260T LE200 to 260ST 60   BOTH=?   W+P-BOTH+N=200 to 260LL   260+300-BOTH+60=420   BOTH=200   now pay attention to the fact, that both at most can be 260, since W=260   so, the answer is 200 to 260
