What was the original price if: after 10% discount it becomes $450?
100-10=90
450=90% of original find 100%
divide by 9
50=10%
times 10
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
\(x-\frac{10}{100}\times x\)
\(\frac{100x-10x}{100}\)=450
\(\frac{90x}{100}\)=450
x=\(\frac{100\times450}{90}\)
On solving
x=500$
The original price =500$
