Oh, come on.
57.50 * .2 = 11.50
57.50 - 11.50 = $46
Take a calculator with you at the store sales.

Ignore the previous responses. They didn't read the question. 20% off 57.50 is NOT 80% of 57.50, it is:
0.2 x 57.50 = $11.5

$57.50 * 20%=1150
1150 / 100%= $11.50
$57.50-$11.50=$46.00

mmm ok if u like want to be good at quick math...
make a habit to learn a daily trick like this..
20% = one fifth.
to divide by five is to double and then move then decimal one place left...
so
20% of 57.50
is one fifth less
is 11.50 less
is 46.00
also mentally practice common (and uncommon) divisions, multiplications, additions, subtractions, roots and everything else you can think of...
psst... this helps you at any SAT/MAT type of test as well later..
guess most ppl go through this a lot...but just mentioned it...
ANSWER : its 11.50 off or a 46.00 price
