Question 274866
"8% use neither" ___ so 92% use one or the other or both


"68% use the running track" ___ so 68% - b use only the track


"44% use the swimming pool" ___ so 44% - b use only the pool


(68% - b) + (44% - b) + b = 92%


112% - b = 92% ___ 20% = b


substituting ___ 68% - 20% = 48% use only track
