To find the discount rate for the prom dress, you can use the formula:

Discount Rate = (Discount Amount / Original Price) * 100

First, you need to calculate the discount amount by subtracting the sale price from the original price:

Discount Amount = Original Price - Sale Price

Discount Amount = $395 - $280 = $115

Then, substitute the values into the formula to get the discount rate:

Discount Rate = ($115 / $395) * 100

Discount Rate ≈ 0.2911 * 100

Discount Rate ≈ 29.1 (rounded to the nearest tenth of a percent)

Therefore, the discount rate for the prom dress is approximately 29.1%.
