x is increased by 100%.

Find the percentage increase in y.

so,

y=k x2

y= k (100 + x2)

then i went to find the k,

which is

k= y/ (100 + x2)

so i put back the k which i found into y= k (100 + x2)

which is :

y= y/(100 + x2) (100 + x2)

them I am stuck here..

somebody pls helppp!

thanks lotsa.
