Let's delve into the calculation:
Understanding 40% Off
40% off represents a reduction of 40 out of every 100 units. To calculate this discount, we first convert the percentage to a decimal. This is done by dividing the percentage by 100: 40% / 100 = 0.40
Applying the Discount
Now, we multiply the decimal (0.40) by the original price (30): 0.40 * 30 = 12. This result, 12, represents the amount of the discount.
Final Price Calculation
To arrive at the final price, subtract the discount (12) from the original price (30): 30 - 12 = 18.
Therefore, 40 percent off of 30 equals 18.
Understanding the Relationship between Percentage and Decimal
Percentages and decimals are closely linked. Percentages represent a fraction out of 100, while decimals express the same fraction in a more compact way. By converting a percentage to a decimal, we can easily perform calculations involving discounts, interest rates, and other percentage-related applications.
