HELP!

OpenStudy (anonymous):

yes?

OpenStudy (nerdgirl):

what's up?

OpenStudy (anonymous):

OpenStudy (anonymous):

well first figure out the total number of bikers

OpenStudy (anonymous):

15 own a bike and 15 don't making 30 in total

OpenStudy (anonymous):

Right

OpenStudy (anonymous):

and figure out how many live near a pool

OpenStudy (anonymous):

18 do, 12 do not

OpenStudy (anonymous):

Okay

OpenStudy (anonymous):

we can eliminate d because 10/30 actually is 1/3 not 2/3

OpenStudy (anonymous):

Alrighty

OpenStudy (anonymous):

and c because 12 is less than half of 30

OpenStudy (anonymous):

Okay

OpenStudy (anonymous):

the answer should be C because 15/30 is 50%

OpenStudy (anonymous):

double checking

OpenStudy (anonymous):

Ok so maybe c?

OpenStudy (anonymous):

wait it is actually a my mistake

OpenStudy (anonymous):

yess

OpenStudy (anonymous):

because 8/15 is over 50%

OpenStudy (anonymous):

we are a team ha

OpenStudy (anonymous):

12/18 is not 50%

OpenStudy (anonymous):

for sure the answer is A

OpenStudy (anonymous):

Thanks!
