In the world of consumer goods, percentages, sales, and discounts have become synonymous with shopping. From clothing to electronics, a percentage off can significantly influence purchasing decisions. But have you ever stopped to think about what that percentage means in actual dollars and cents? Today, we're diving deep into one such calculation: 20% of $32, uncovering the mystery and demystifying this common sales tactic.
Understanding Percentages
Before we delve into the specifics of 20% of $32, let's first refresh our memory on what percentages are:
Percentages are a way to express a number as a fraction of 100. So, when you see "20%", it's essentially 20 per 100 or 1/5.
Here's how you calculate a percentage:
- To find a percentage of a value, multiply the percentage by the number.
For example, if you want to find 20% of $100:
- (20/100) * $100 = $20
Real-life Applications of Percentages:
- Discounts: You often see stores promoting "20% off" or "20% extra savings."
- Interest Rates: When borrowing money, the interest rate is often expressed as a percentage.
- Tax Rates: Sales tax or income tax is calculated as a percentage of the price or income.
