When calculating "15 off 200," it is commonly interpreted as a percentage discount. The exact answer, when calculating 15 percent off 200, is 170.
Understanding "15 Off 200"
In common usage, especially in retail and pricing, "15 off [a number]" typically signifies a 15 percent reduction from that number. This means you need to first calculate 15 percent of the original value (200) to find the discount amount, and then subtract that amount from the original value.
Calculating the Discount
To determine the final amount after a 15 percent discount from 200, follow these steps:
Step-by-Step Calculation:
- Calculate the discount amount: Find 15 percent of 200.
- To do this, convert the percentage to a decimal (15% = 0.15) and multiply it by the original amount:
0.15 * 200 = 30
- This means that 15 percent of 200 is 30. If you were buying an item, like a $200 television that was on sale at 15% off, you'd receive a $30 discount from the original price.
- To do this, convert the percentage to a decimal (15% = 0.15) and multiply it by the original amount:
- Subtract the discount from the original amount:
- Take the original amount and subtract the calculated discount:
200 - 30 = 170
- Take the original amount and subtract the calculated discount:
Therefore, 15 off 200 is 170.
Practical Example:
Imagine you find a product, such as a high-quality speaker, originally priced at $200. If it's advertised as "15% off," you would:
- Determine the savings: 15% of $200 is $30.
- Calculate the final price: Subtract the $30 discount from the original $200.
- $200 - $30 = $170
You would pay $170 for the speaker.
- $200 - $30 = $170
