Answer:
$525
Step-by-step explanation:
We can find the original price by using the formula x - 0.36x = 336, where x is the original price, 0.36 is the discount percentage (converted to decimal form), and 336 is the total amount paid after the discount is applied:
![x-0.36x=336\\0.64x=336\\x=525](https://tex.z-dn.net/?f=x-0.36x%3D336%5C%5C0.64x%3D336%5C%5Cx%3D525)
To check and further understand why the formula works, we can simply apply the discount to the original price and subtract the number from the original price:
525 * 0.36 = 189
525 - 189 = 336
Modeling the first formula gives us:
525 - (0.36 * 525) = 336
525 - 189 = 336
Answer:
