A woman received a discount of 20% on a piece of cloth she purchased from a shop. If she paid $525.00, what was the original price?
$675.25
$660.25
$656.25
$616.25
Explanation
\(\frac{20}{100}\) x \(x\) = \(x - 525\)
\(\frac{x}{5} = x\) - 535
x = 5x - 2625
\(\frac{4x}{4} = \frac{2625}{4}\)
x = $656.25
