How To Calculate A Discount Sale Price

Calculating a discount sale price is one of the most useful mathematics skills people should learn. When you go to a store or a restaurant and see a discount offer, you should think of how much money you could save. In this way, you can get better control of your money. And, from time to time, you will find you become richer and richer. Let’s talk about how to compute a discount sale price.

For example, an item has a 75% off.
Sale price = (1-75%)*regular price

In the example above, we didn’t consider tax. Usually, when we buy things, tax applies. So, the formula should be:
Sale price = (1-75%)*regular price*(1+tax)

I think most people need a calculator when doing such a trivial calculation. But doing it with a regular calculator is too trivial. You need to remember all that formulas. And even if that’s not a hard job for you, it still wastes your time to enter all the formula into the calculator.

How to calculate tips

Tipping is expected in American restaurants. Calculate a tip is not a hard task, but it’s annoying. In United States, the average tip is usually around 15% of the total bill before tax. Just multiply the total bill before tax by 15%, you will get the tip amount.

If you find that’s too trivial, here is the solution.

Use a tip calculator to compute your tip, simple and quick. I would recommend Calculate Tip - Easy Fast Restaurant Gratuity Calculator Free
