m + f = number of participants last year
1.1(m + f) = number of participants this year
1.05m + 1.2f = also the number of participants this year
so ... what now?
Participants in the local soccer league this year is 10% greater than it was last year. The number of males increased by 5%, and the number of females increased by 20%. What fraction of the soccer league is now female?
I just can't seem to get this problem started....
solving for m I get:
(1/11)f = 1/22 m
2f = m
Okay, so 1/3 of the participants are female.
Holy cow, that was so simple. Ive been working on it all day...and thinking too hard about it. haha
Thank you so much!
