Decoding Successive Discounts: How to Calculate Equivalent Single Discounts

When we talk about discounts, we’re often faced with the question of how two discounts work together. It sounds complicated at first, but getting a handle on successive discounts isn't just valuable knowledge for the retail shopper. It's also an essential skill for anyone wanting to maximize savings. So, let’s break down the process and make sense of those numbers!

Imagine you’re eyeing that perfect jacket that’s originally priced at $100. You notice it’s marked down—first by 20% and then by another 10%. But what’s the best savings you can actually achieve? You’re probably wondering, “What’s the equivalent single discount here?” Spoiler alert: it’s 28%. But how did we get there?

Start with the First Discount

To tackle this, let’s take a step-by-step approach. You start with your original price: $100. Next, you apply your first discount of 20%. Here’s how the math works:

• Calculate 20% of $100:
  [ \text{Discount} = 20% \text{ of } 100 = 20 ]
• New Price After First Discount:
  [ \text{New Price} = 100 - 20 = 80 ]

So far, so good! Your jacket is now priced at $80. But that’s not the end of the savings journey. You’ve got another discount on the way!

Time for the Next Discount

Now it’s time to apply a second discount of 10% to your new price of $80. Here’s where things can get a little fuzzy if you’re not paying attention, but we’ll take it slow:

• Calculate 10% of $80:
  [ \text{Discount} = 10% \text{ of } 80 = 8 ]
• New Price After Second Discount:
  [ \text{New Price} = 80 - 8 = 72 ]

At the seat of this equation, your jacket is now $72. But how remarkable is that? You’ve knocked $28 off the original price!

Finding the Equivalent Single Discount

Now that you've found the final sale price, let’s revisit that curiosity of finding an equivalent single discount. To do that, we need to compare the final price with the original price.

1. Original Price: $100
2. Final Price: $72
3. Discount Amount:
   [ \text{Discount Amount} = 100 - 72 = 28 ]

Now we want to figure out what percentage of the original price $28 is. Let’s throw in some simple math:

[ \text{Equivalent Single Discount} = \left(\frac{\text{Discount Amount}}{\text{Original Price}}\right) \times 100 ]
Substituting in our numbers, we get:
[ \text{Equivalent Single Discount} = \left(\frac{28}{100}\right) \times 100 = 28% ]

And there you have it! The equivalent single discount for those successive discounts of 20% and 10% is indeed 28%. But why stop here?

Why Understanding Discounts Matters

Knowing how to calculate these discounts is not just a numbers game; it’s about making informed decisions. Think about it—a savvy shopper can navigate sales, clearances, and promotions with confidence. Whether it’s buying clothes, electronics, or even services, these calculations come in handy.
