A group of boy scouts and girls scouts is going on a rafting trip. 60% of the scouts arrived with signed permission slips. If 45% of the scouts were boy scouts and 50% of the boy scouts arrived with signed permission slips, then what percentage of the girl scouts arrived with signed permission slips? Round to the nearest percent.	Choose the correct option:
A) 64
B) 68
C) 72
D) 76
E) 80
45% were boy scouts so 55% (100-45=55) were girl scouts.   # of boy scouts with permission slips signed + # of girl scouts with permission slips signed = total # with permission slip signed   (50% of 45% of the total going) + (?% of 55% of the total going) = 60% of the total going   We can let the "total going" = 1,000 arbitrarily since we only care about the percent (of girl scouts w/ permission signed)   .50*.45*1,000 + x*.55*1,000 = .60*1,000   225 + x*550 = 600   550x=375   x=375/550=

.6818181818 which converts to a percent of 68.18181818% which rounds to 68%   68
