An electronics store had a 20% off sale. If a stereo originally cost $125, how much did the stereo cost during the sale?<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

Answer:<\/strong>
The stereo cost $100<\/strong> during the 20% off sale.<\/p>\n\n\n\n

Explanation<\/strong><\/h3>\n\n\n\n

To find the sale price of the stereo during a 20% off sale, we begin by understanding what a discount means. A 20% discount means the customer pays 20% less than the original price.<\/p>\n\n\n\n

The original price of the stereo is $125<\/strong>. We calculate 20% of $125<\/strong> to determine how much money is taken off the original price during the sale.<\/p>\n\n\n\n

To find 20% of $125, we convert the percentage to a decimal and multiply:20%=20100=0.2020\\% = \\frac{20}{100} = 0.2020%=10020\u200b=0.20Discount=0.20\u00d7125=25\\text{Discount} = 0.20 \\times 125 = 25Discount=0.20\u00d7125=25<\/p>\n\n\n\n

So, the store gives a $25<\/strong> discount.<\/p>\n\n\n\n

Now, we subtract the discount from the original price to find the final sale price:Sale Price=125\u221225=100\\text{Sale Price} = 125 – 25 = 100Sale Price=125\u221225=100<\/p>\n\n\n\n

Thus, the stereo costs $100<\/strong> during the sale.<\/p>\n\n\n\n

\n\n\n\n

Why Understanding Discounts Is Important<\/strong><\/h3>\n\n\n\n

Understanding how discounts work helps consumers make smart financial decisions. In real-life scenarios, stores often use percentages to show savings during sales. Knowing how to calculate these savings allows shoppers to judge whether a deal is truly worthwhile.<\/p>\n\n\n\n

Also, understanding percentages is an essential part of financial literacy. Discounts, interest rates, tax, and tips all involve percentage calculations. For example, if a product is taxed at 8%, a shopper should be able to calculate the total cost after tax.<\/p>\n\n\n\n

In this case, knowing how to subtract 20% from the original price helps a buyer recognize that the stereo costs significantly less during the sale. It also enables them to budget better, perhaps buying other items with the money saved.<\/p>\n\n\n\n

So, the stereo\u2019s final cost of $100<\/strong> is not only the result of a simple math calculation but also an example of real-world math application in everyday shopping.<\/p>\n\n\n\n
