Calculating Discounts & Markups
Ever wonder how to figure out sale prices? A discount is when the price goes DOWN from the original price, while a markup is when a store increases the price from what they paid (price goes UP).
There are two ways to solve these problems. First, you can find the discount amount and subtract it from the original price. For example, if shorts originally cost 35 = 26.25.
The second way is faster - just multiply by the remaining percentage. For the same shorts, 100% - 25% = 75%, so you calculate 75% of 26.25 and get the same answer!
Helpful Tip: When you need to find the original price from a sale price, divide the sale price by the remaining percentage (as a decimal). For example, if shoes are 40% off and now cost 33 ÷ 0.60 = $55 original price.

Working with Multiple Percentage Changes
When stores mark up items, they add a percentage to their cost. If a store pays 70 = 84 selling price. A quicker way is calculating 120% of 84.
Discounts can be applied multiple times. For a 77.70. If there's another 60% off that price, you'd calculate 40% of 31.08. The stereo isn't free - it's $31.08!
Remember that tax gets added after discounts. For jeans that normally cost 39.99 = 29.99 = $31.94 total.
Quick Trick: Draw a plus sign (+) next to markup or tax calculations to remember you're adding them, and a minus sign (-) next to discount calculations to remember you're subtracting.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
