Find the regular price. Round to the nearest cent . Sales price is 56.78 percent discount is 40%

LenaWriter [7]

$100\%-40\%=60\%\\60\% = \frac{60}{100}=\frac{6}{10}=\frac{3}{5}\\\\$

Numerator is 3 and denominator is 5. So, we divide the sales price by 3 and we multiply by 5 to get the whole fraction, or 100%.

$\frac{56.78*5}{3} \\\frac{283.9}{3} \\94.6333333333333...$

Your regular price sounds recurring, so you might have made a mistake copying.

The answer for what you've got is 94.633333...
