The price of a car has been reduced from $11,000 to $8,690. What is the percentage decrease of the price of the car?

(11,000-8690)/11,000 = ?

(11000-8690)/11000 * 100 = 21%

To calculate the percentage decrease of the price of the car, you can follow these steps:

1. Determine the amount of decrease: Subtract the reduced price from the original price.
Decrease = Original Price - Reduced Price

In this case:
Decrease = $11,000 - $8,690 = $2,310

2. Calculate the percentage decrease: Divide the amount of decrease by the original price and then multiply by 100.
Percentage decrease = (Decrease / Original Price) * 100

In this case:
Percentage decrease = ($2,310 / $11,000) * 100 ≈ 21%

Therefore, the price of the car has been reduced by approximately 21%.
