let the regular price be P
P x (100-20)/100 = $1600
P x 0.8 = 1600
therefore, P= 1600 x 0.8
P= 2000

$2000
If it's 20% discount off of the regular price, that means the new sale price is 80% of the regular price.
$1600 = 80% of regular price
"of" implies multiplication
"regular price" is "x" in equation below
Therefore:
$1600 = 80% * x
>>>>>>>> $1600 = .80x
>>>>>>>> $1600 / .80 = (.80x) / .80
>>>>>>>> $2000 = x
Regular price = $2000

Divide by 80 as it's only an eightieth of the full price then multiply by 100 to get the full price.
1600 / 80 = 20
20 x 100 = 2000

80%<--->$1600
100%<--->(100 / 80) x $1600
= 5 / 4 x $1600
= $2000
Regular price = $2000

$2000
if you work it out, 1600 is the eighty percent that is left after the discount, so divide by .8 and you have your answer, this is the same as using the fraction 80/100 (=.8 = 80 %), you are essentially dividing 1600 by 80 to find one percent and then multiplying that answer by 100 to find the total original cost

Because its selling at 80% of its normal price then the discounted price is 0.8P
0.8P=1600
P=1600/0.8
P=2000
Regular price is $2000.

20% is the discount and 80% of the original price is the discounted price. So,
0.80(X)=1600
X=$2000

X x (1-0.2)=1600
1600/0.8=X
X=2000
