original price = $48
In terms of percentages the original price is 100% and the purchase price is 70% ( that is 30% less than 100% = 70% )
divide the purchase price by 70 to find 1% and multiply by 100 to obtain original price
original price = [tex]\frac{33.60}{70}[/tex] × 100 = $48
So if the used a 30% off coupon she paid 70% of the original price so we can set up a proportion to solve
[tex]\frac{0.7}{33.60} = \frac{1}{x} [/tex]
We can solve to find that x = 48 so the original price was $48
[tex]\frac{0.7}{33.60} = \frac{1}{x} [/tex]
We can solve to find that x = 48 so the original price was $48
