Uses of Percentages in Everyday Life

It’s a fundamental notion in everyday utility mathematics that streamlines many facets of being alive. This article will thus focus on the places where we often interact with percentages and how to do so. See below for details.

1. How to Figure Out Restaurant Gratuities

We make frequent trips to the mall in search of various necessities. This way, the concept of bartering money for goods is accessible to everyone.

2. To Determine the Applicable Sales Tax Rate

Since sales tax is included in every purchase and is collected legally, it is crucial to understand how it works. To understand the total cost of an item, children can practice this concept by multiplying the price of the item by the applicable sales tax rate. To illustrate, say you want to buy a $25 blouse, but the local sales tax is 6%. Multiply the shirt’s price by 0.06 to estimate the tax. Therefore, $1.50 total includes taxes on that garment.

3. Tool for Calculating Price Cuts

If a blouse costs typically $50 but sells for $20 off, you would multiply the original price by 0.2 to get the price after the reduction. For this scenario, you will receive $10 (20% of $50). It would cost $40 to buy the shirt in its entirety.

You’d have a 25% batting average.

5. Findings of the Survey

The findings of surveys are frequently reported in numerical form, typically as a percentage. Bar charts and pie charts make it easy to see the rates that accompany these numbers. This is for the sole purpose of clarifying the findings of the research. For instance, if you take a group of 50 people and divide them by their preferred cuisine, you’d find that 10% prefer Asian food, 30% prefer Italian, 5% prefer Mexican, 25% prefer fast food, and 30% prefer healthier options.
