wat do u mean by ur question? if the price goes down by 5.8% say for example $25 that will be $23.55.

then the rate that it should increase to be $25 again

if that's it, then you'll need $1.45 for it be $25 again.

$\displaystyle R=\frac{P}{B}$

$\displaystyle R=\frac{1.45}{23.55}$

$\displaystyle R=6.15\%$

i'm not really sure bout it. correct me if I am wrong. :) - Feb 3rd 2009, 11:45 PMjavax
Let v1 be the first price, v2 the second(down price), p2 be the percentage required.

now you have

$\displaystyle v1-0.058v1=v2$

$\displaystyle v2+p2 v2=v1$

From here you can find p2, which is the percentage required. (answer p2 = 6.15%). As it is mentioned in the above post. - Feb 3rd 2009, 11:47 PMprincess_21
