Final answer:

The percent decrease is 10%.


Step-by-step explanation:

To find the percent decrease, we use the formula:

% Decrease = ((Original Price - New Price) / Original Price) x 100%

Using the given information, the original price was $800 and the new price is $720.

Plugging these values into the formula:

% Decrease = (($800 - $720) / $800) x 100% = (80/800) x 100% = (1/10) x 100% = 10%

Therefore, the percent decrease is 10%.
