Final answer:
To find the percent decrease, subtract the sale price from the original price and divide by the original price. Multiply the result by 100 to get the percentage.
Step-by-step explanation:
To find the percent decrease, we need to find the difference between the original price and the sale price, and then divide that difference by the original price. In this case, the original price is $50.00 and the sale price is $30.00, so the difference is $50.00 - $30.00 = $20.00. Next, we divide the difference by the original price, which gives us $20.00 / $50.00 = 0.4. Finally, we multiply the result by 100 to get the percentage: 0.4 * 100 = 40%. So, the percent decrease is 40%.
