Everyday situations like shopping often require us to use percentages. Here are some important ways we use them:
Discounts: Imagine you want to buy something that costs 100, and there's a 20% discount. To find out how much you save, you do this calculation: $$100 \times 0.20 = 20$$ So, you save 20. This means the final price you pay is $80.
Sales Tax: In Sweden, the usual sales tax is 25%. If you buy something for 100, the tax would be: $$100 \times 0.25 = 25$$ That means, in total, you will pay 125.
Percentage Increase: If a product goes up in price from 65, we can find out how much it has increased:
This tells us the price increased by 30%.
Learning how to use these calculations helps us make better choices when we spend money.
