To find the percent decrease, you can use the formula:
Percent Decrease = ((Original Price – New Price) / Original Price) * 100
In this case, the original price of the dress was 60 and the new price is 51. Let’s plug these values into the formula:
Percent Decrease = ((60 – 51) / 60) * 100
First, calculate the difference between the original price and the new price:
60 – 51 = 9
Now, divide the difference by the original price:
9 / 60 = 0.15
Finally, multiply by 100 to find the percentage:
0.15 * 100 = 15
So, the percent decrease in the price of the dress is 15%.
