Answer:

$450 is the original price

Step-by-step explanation:

We can create a proportion to find the sale on the original price. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the prices and percents. It is marked down by 30% so we pay 70% of the original. The sale price is $315.

\frac{70}{100} =\frac{315}{x}

We begin solving by cross multiplying numerator to denominator of each fraction.

70(x)=100(315)\\70x=31500\\\frac{70x}{70}=\frac{31500}{70}  \\450=x
