New York City is in New York, so the boys who live in NYC are also living in NY State. This means that 20% of the 30% New Yorkers are NYCians. .2*.3 = .06, so the answer is "e. 6%".
B = # of boys in camp.
0.3B = # of boys from N.Y.S.
0.2 * 0.3B = 0.06B=# of boys from N.Y.C.
(0.06B/B)*100% = 6% = Percentage of
boys in camp from N.Y.C.
0.3B = # of boys from N.Y.S.
0.2 * 0.3B = 0.06B=# of boys from N.Y.C.
(0.06B/B)*100% = 6% = Percentage of
boys in camp from N.Y.C.
