K = 4pq^2
k/4p = q^2
0.5(k/p)^1/2 = q
4/6 = 1/x cross multiple so x= 1.5 dollars
I THINK ITS B or A BUT I AM NOT SURE
lets say there are 100 girls.
4/5 of 100 is 80, so 80 girls have brown hair.
3/4 of the 80 who have brown hair have long hair.
3/4 of 80 is 60.
so we know that out of 100, 60 have long brown hair.
in simplest fraction form, 60/100= 3/5
