There was a $1200 x 10/100 = $<<1200*10/100=120>>120 increase of the original price.
So, the perfume was priced for $1200 + $120 = $<<1200+120=1320>>1320.
Then, 15% of the new price is $1320 x 15/100 = $<<1320*15/100=198>>198.
So, the final price is now $1320 - $198 = $<<1320-198=1122>>1122.
Therefore, the final price is $1200 - $1122 = $<<1200-1122=78>>78 lower than the original price.
