Can you explain what is incorrect here:
price in 2001: p
price in 2002: (1.0x) * p
price in 2003: (1.0y) * (1.0x) * p
% change = [ (new) - (old) ] / old
Now this is where I faltered: to multiply say 1.01 and 1.03 .
Is the best strategy to use fractions ie % (means to divide by 100)
I found (1+a) (1+b) = 1 + a + b + ab
too prone to mistake in calculations.
Let me know if there is any other approach that I can take?
Hey i would like to know what exactly did u mean by this :
price in 2001: p
price in 2002: (1.0x) * p
price in 2003: (1.0y) * (1.0x) * p
i think u consider (X) a single digit .... for example if x= 5%
then price in 2002- 1.05 *p
if (X) is a two digit integer then.... for example if x=20%
the price in 2002- 1.2*p
this is where i guess u did a mistake.... its better like this - (100+x/100)*p
