100%<------->$57
80%<--->(80/100) x $57
= 4/5 x $57
= $ 228 / 5
= $ 45 . 60
OR
10% = $5.70
20% = $11.40
Sale price = $57 - $11.40 = $45 . 60

Find the amount when the base and percent are known.
Amount = base x percent
Divide 20 / 100 to get the decimal
20 / 100 = 0.2
Multliply 57 times the decimal
57 x 0.2 = 11.4
The amount is $ 11.40
$ 11.40 is 29% of $ 57.00

Subtrace $ 11.40 from $ 57.00
57.00 - 11.40 = 45.60
The price of the dress after deduction is $ 45.60

57.00 x .20 = $11.40. Do you think that you didn't get enough money back? You do know that the 20% is taken off before the taxes are calculated, right?

57 * .8 = 45.6
I used .8 to stand for 80% (because you got 20% off, 100 - 20 = 80) so you paid $45.60 without tax.
The flaw in other people's math...
57 * .2 = 11.4
that is 20% of $57
but it just goes to show my math is correct:
57 - 11.4 = 45.6

$57 * 20% = $11.40
Answer: 20% off is $11.40.
You'd be paying $57.00 - $11.40 or $45.60 only.
