Math in Action: Mastering Discounts & Sales Prices

** **

Let's Get Started with the Basics

** Imagine you're at *Bugis Street Market*, Singapore's famous shopping paradise. You spot a beautiful *tekka* (singlet) for $30. But hold on, the auntie says it's on sale! How much can you save? Let's find out. In Singaporean rigorous post-primary schooling landscape, the shift from primary school introduces pupils to more complex mathematical concepts including basic algebra, integers, and principles of geometry, that can be daunting without adequate preparation. A lot of parents emphasize extra support to close any gaps while cultivating an enthusiasm toward mathematics early on. p6 maths tuition provides focused , Ministry of Education-compliant classes using qualified tutors that highlight problem-solving strategies, individualized feedback, plus interactive exercises to develop basic abilities.

List Price: The Starting Point

** The *list price*, or *original price*, is like the starting point in our *tekka* story. It's the price before any discounts or sales. In our case, the list price is $30. **

Discount: The Magic Number

** Now, imagine Auntie wave her magic wand and says, "20% off for you, dear!" A *discount* is a percentage reduction from the list price. To calculate it, you multiply the list price by the discount percentage:

Discount = List Price × (Discount Percentage / 100)

So, for our *tekka*:

Discount = $30 × (20 / 100) = $6

**

Sale Price: The Final Deal

** The *sale price* is what you pay after the discount. It's the list price minus the discount:

Sale Price = List Price - Discount

So, our *tekka* now costs:

Sale Price = $30 - $6 = $24

**

The term 'ratio' comes from the Latin word 'ratus', which means 'reckoned' or 'calculated'.

**Proportion: When Ratios Become Equal**

Now, let's talk about proportion. It's like finding the perfect proportion of kaya to kopi in your kopi peng. In shopping, it helps you find out if two quantities are in the same ratio, or in other words, if they're giving you the same value for your money. Let's say you want to compare the value of two packs of Milo. Pack A is $3 for 400g, and Pack B is $4 for 500g. The ratio of their prices is 3:4, and the ratio of their quantities is 400:500, or simplified, 4:5. To check if they're in proportion, you can divide the price ratio by the quantity ratio: (3/4) ÷ (4/5) = 1.5. This means Pack A gives you 1.5 times less Milo for your money than Pack B.

**Real-World Applications: Math in Action**

  • Discounts: Understanding ratios and proportions helps you calculate discounts quickly. For instance, if an item is 30% off, you just need to calculate 30/100 of the original price.
  • Sales Prices: Ever seen a price like $19.90 and wondered if it's actually $20? Knowing that $10 is to $1 as $9.90 is to $10 helps you see that $19.90 is just a cent less than $20.

Fun fact: The concept of 'going on sale' originated in the 19th century when shopkeepers would literally put their goods on the street (or 'sidewalk') to sell them at discounted prices.

**Your Mission, Should You Choose to Accept It**

Next time you're at Golden Mile Complex or Tekka Market, put your secondary 1 math skills to the test. See if you can find the best deals by comparing prices and calculating discounts. Remember, every cent saved is a cent earned, and who knows, you might just become the shopping hero of your family or class!
