It's a common sight on price tags and online ads: a percentage off a dollar amount. But sometimes, the way we read it can get a little jumbled. Let's clear up a common query: what exactly is 20% off $25?
Think of it like this: you're at a store, and a sweater you like is marked at $25. The sign proudly proclaims "20% off!" This means the store is taking away 20 percent of that original $25 price. So, the first step is to figure out how much that 20 percent actually is.
To do that, we convert the percentage into a decimal. Twenty percent (20%) is the same as 20 divided by 100, which gives us 0.20. Now, we multiply this decimal by the original price: 0.20 * $25.
Doing that math, we find that 20% of $25 is $5. This $5 is the amount of the discount – it's what gets subtracted from the original price.
So, to find out how much you'll actually pay, you subtract that discount from the original price: $25 - $5.
And there you have it: the final price is $20.
Alternatively, you can think about it from the perspective of what you are paying. If you're getting 20% off, it means you're paying the remaining 80% of the original price (100% - 20% = 80%). So, you could also calculate 80% of $25. Converting 80% to a decimal (0.80) and multiplying by $25 (0.80 * $25) also gives you $20. Both methods lead to the same, satisfyingly lower price!
