A stereo system is marked down from $450.00 to $382.50.What is the discount rate?
change = 67.5
discount rate = 67.50/450 = .15 = 15%
To calculate the discount rate, we need to determine the amount of discount first.
Discount = Original Price - Sale Price
Discount = $450.00 - $382.50
Discount = $67.50
Now, we can calculate the discount rate using the formula:
Discount Rate = (Discount / Original Price) * 100
Discount Rate = ($67.50 / $450.00) * 100
Discount Rate = 0.15 * 100
Discount Rate = 15%
Therefore, the discount rate of the stereo system is 15%.
