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.
We begin solving by cross multiplying numerator to denominator of each fraction.
6x+8=-3x-10
9x=-18
x=-2
-3(-2)-10=-4
So x=-2 and y=-4
