How can I solve this:
If a certain price goes down 5,8%
how many procents the price should
rise that it would be as much as it
used to be.
Thank you!
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.
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.
