origianl price=$500 (this is the hack way that only works with nice numbers)

Answer: Original Price=$450


Step-by-step explanation:

Price post discount=$450

Discount=10%

Let the original price be x

Given x - 10% of x=450

\(x-\frac{10}{100}\times x\)

\(\frac{100x-10x}{100}\)=450

\(\frac{90x}{100}\)=450

x=\(\frac{100\times450}{90}\)

On solving

x=500$

The original price =500$
