100-10=90

450=90% of original find 100%

500=100%
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

[tex]x-\frac{10}{100}\times x[/tex]

[tex]\frac{100x-10x}{100}[/tex]=450

[tex]\frac{90x}{100}[/tex]=450

x=[tex]\frac{100\times450}{90}[/tex]

On solving

x=500$

The original price =500$
