Find the decrease in the price as a percent:
if regular price is $135 and sale price is $83.00+, then the regular price has decreased by x% or x%2F100 of 135 and you got sale price of $83.00+
an equation for it is: 135-%28x%2F100%29135=83
solve for x
135-%28135x%2F100%29=83
135-83=135x%2F100
52=135x%2F100
52%2A100=135x
5200%2F135=x
x=38.52% or 38.52%2F100
check:
regular price is $135
38.52% of it is $135%2838.52%2F100%29=135%2A0.3852=52.002=52
now subtract $52 from the regular price
$135-52=83 and you got sale price of $83.00+
