What is the percentage?</h3>
In mathematics, a percentage is a number or ratio that is expressed as a fraction of 100.
Although "pct," "pct," and occasionally "pc" are also employed as acronyms, the percent symbol "%" has been most usually used to denote it.
A% is a number that has neither dimensions nor a specified unit of measurement.
For example, if you properly completed 75 out of 100 questions on a test, you would have received a 75% grade (75/100).
So, in mathematics, a percentage is a number or ratio that is expressed as a fraction of 100. Let x represent the initial asking price ( in dollars ),
After 10% is deducted, 10% of x less the new selling price, or x - 0.1x, equals 0.9x.
Having reduced the price by 30%,
The final selling price equals 90% less than 90%.
= 0.9x - 0.3 × 0.9x
= 0.9x - 0.27x
= 0.63x
The answer to the query is:
0.63x = 325
x = 325/0.63
x = 515.87
Therefore, using percentages, we know that $515.87 approx is the purchase price at the start.
