let C = the cost of the item originally
the question tells you that
15% of C = 12 dollars
or (15/100)C = 12
C = 80
so the original cost of the item is $80

If 15% of the original price is 12
then 1% of the original price is 12/15= 0.8
If 0.8 is 1% then 100% is 0.8x 100= 80
Then the original price of the item is 80 dollars
I hope this helps

Find the base when the amount and percent are knows.
amount / percent = base
convert 15% to decimal
remove the % sign. divide 15 by 100
15 / 100 = 0.15
divide 12 by the decimal
12 / 0.15 = 80
$ 12 is 15 % of $ 80

If 12 dollars represents 15% of the original price, then, to get the original price, divide 12 by 0.15 (because % means per 100) and you get the answer 80 dollars.

item y when it is regular after 15% will be y-15/100y
so y -(y-15/100y)=12
y-y+15/100y=12
15/100y=12
y =12/(15/100)=12*100/15
y=12*20/3=4*20=80
it was 80 dollars

15% of the items cost is $12
that should help you determine the price
I'm not going to tell you the answer because
1) you said so i can just help you find the answer
and 2) to stimulate your brain!
but the d0uch3 above me already gave you the answer.
