rosa wants to buy a computer desk that originally cost $650. It has been marked down to a new price of $520. What is the percent off?
$650 - $520 = $130
650x = 130
x = 130/650 = 0.2 = 20%
idk
20% I just guessed
To calculate the percent off, you need to find the difference between the original price and the new price, then divide that difference by the original price, and finally multiply the result by 100.
Step 1: Find the difference between the original price and the new price:
Difference = Original Price - New Price
Difference = $650 - $520
Difference = $130
Step 2: Divide the difference by the original price:
Percentage off = (Difference / Original Price) * 100
Percentage off = ($130 / $650) * 100
Percentage off = 0.2 * 100
Percentage off = 20
Therefore, Rosa is getting a 20% discount on the computer desk.
