To calculate the discount rate, we need to find the difference between the original price and the marked-down price, and then divide that difference by the original price. The formula to calculate the discount rate is:
Discount Rate = (Original Price - Marked-Down Price) / Original Price
In this case, the original price is $450, and the marked-down price is $382.50. By substituting these values into the formula, we can calculate the discount rate:
Discount Rate = ($450 - $382.50) / $450
Discount Rate = $67.50 / $450
To find the discount rate as a percentage, we can convert the result to a decimal by dividing the numerator by the denominator, and then multiplying by 100:
Discount Rate = ($67.50 / $450) * 100
Discount Rate = 0.15 * 100
Discount Rate = 15%
Therefore, the discount rate for the stereo system is 15%.
