Yesterday, the price of a car Andy wanted to buy was $20,000. Today the car is on sale for $15,000.00. What is the percent decrease in the price of the car?

(5/20)100 = 25%

To find the percent decrease in the price of the car, you need to calculate the difference between the original price and the sale price, and then express it as a percentage of the original price.

First, subtract the sale price ($15,000.00) from the original price ($20,000.00):

$20,000.00 - $15,000.00 = $5,000.00

Next, divide this difference ($5,000.00) by the original price ($20,000.00):

$5,000.00 / $20,000.00 = 0.25

Finally, multiply the result by 100 to express it as a percentage:

0.25 * 100 = 25%

Therefore, the price of the car has decreased by 25%.
