A $50 computer program is on sale for $37.50. What is the percent decrease?

50-37.50=p

p/50 - x/100

That should help.

decrease is $13

percentage decrease = 13/50 = .26 or 26%

$13 decreases

So 13/50 = .26 = 26%

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

Step 1: Find the difference between the original price and the sale price.
Original price - Sale price = $50 - $37.50 = $12.50

Step 2: Express the difference as a percentage of the original price.
Percentage decrease = (Difference / Original price) * 100
Percentage decrease = ($12.50 / $50) * 100
Percentage decrease = 0.25 * 100
Percentage decrease = 25%

Therefore, the percent decrease is 25%.
