Percentage: Percent, Profit, Discount and Interest
A short read for Class 8 before you play. These notes cover Percentage.
💯 What percent means
Percent means out of 100. We write 40 out of 100 as 40%, as the fraction 2/5 and as the decimal 0.4. To find a percentage of a number, write the percent over 100 and multiply, so 25% of 80 is 20. A percentage can be more than 100, and 150% of a number is one and a half times the number.
💰 Profit, loss and discount
Profit is the selling price minus the cost price, and loss is the cost price minus the selling price. Profit and loss percentages are always found on the cost price. A discount is a percentage of the marked price, so the price you pay is the marked price minus the discount.
🏦 Percent change and interest
Percent change is the change divided by the original value, times 100. Simple interest is principal times rate times time over 100. Compound interest adds the interest to the principal each year, so later years earn more, and 1000 at 10% becomes 1210 after 2 years.

What does percent mean?
Percent means out of 100. For example 40% means 40 out of 100, which is the fraction 2/5 or the decimal 0.4.
How do you find the profit percent?
Profit percent = profit / cost price × 100. A profit of 100 on a cost of 400 is 25%.
How is a discount calculated?
The discount is a percentage of the marked price. The selling price is the marked price minus the discount, so 15% off 800 gives 680.

Simple interest is earned only on the principal. Compound interest is earned on the principal and on the interest already added.
