Calculating discounts is a common task, whether you're shopping online, comparing prices, or just practicing your math skills. This article will clearly explain how to figure out what 30 percent off 200 is, and provide a simple formula you can use for any percentage discount.

Understanding Percentage Discounts

A percentage discount represents a reduction in the original price of an item. In this case, we want to find out how much 30% off of $200 is. This means we need to find 30% of $200 and then subtract that amount from the original price.

Calculating 30% of 200

There are two main ways to calculate this:

Method 1: Using Decimal Conversion

1. Convert the percentage to a decimal: To convert 30% to a decimal, divide by 100: 30% ÷ 100 = 0.30

2. Multiply by the original price: Multiply the decimal (0.30) by the original price ($200): 0.30 x $200 = $60

This means that 30% of $200 is $60.

Method 2: Using Fractions

1. Convert the percentage to a fraction: 30% can be expressed as 30/100, which simplifies to 3/10.

2. Multiply by the original price: Multiply the fraction (3/10) by the original price ($200): (3/10) x $200 = $60

This again shows that 30% of $200 is $60.

Finding the Final Price

Now that we know 30% of $200 is $60, we can calculate the final price after the discount:

Original Price - Discount = Final Price

$200 - $60 = $140

Therefore, the final price after a 30% discount on $200 is $\boxed{140}.

The General Formula for Percentage Discounts

You can use this formula for any percentage discount calculation:

(1 - Percentage Discount/100) x Original Price = Final Price

In our example:

(1 - 30/100) x $200 = $140

This formula allows for quick and easy calculation of discounted prices.

Frequently Asked Questions (FAQs)

Q: How do I calculate a different percentage discount? Simply substitute the new percentage for 30% in the formula above. For example, to find 15% off $200, you would use (1 - 15/100) x $200.

Q: What if the discount is expressed as a fraction (e.g., 1/3 off)? Convert the fraction to a decimal or percentage before using the formula above. 1/3 is approximately 0.333 or 33.3%.

Q: Can I use this for discounts on items with sales tax? No, this calculation only determines the discounted price before tax. Sales tax will be applied to the discounted price.

By understanding these simple methods, you can confidently calculate any percentage discount and save money on your purchases!
