ok so here is the problem....

the price of a music cd was first increased by 15 percent and then the new price was decreased by 30 percent. the final price was what percent of the initial price?

ok so to do this problem i set up my notation...

C = price of cd

ok so then i said....

(C +.15C) = new price

new price = N

N-.3N or...

(C+.15C)-.3(C+.15C)=.76C

i dunno my book says this is wrong, but im not sure where i went wrong...

any help would be appreciated, thanks!
