Final answer:
To find the final price of the dress after the 40% discount, calculate the sale price and apply the additional discount.
Step-by-step explanation:
To find the final price of the dress after the 40% discount, we need to first calculate the sale price and then apply the additional discount. The sale price of the dress can be calculated by subtracting the original discount from the original price:
Original sale price = $130 - (40% of $130) = $130 - ($130 imes 0.40) = $130 - $52 = $78
Next, we apply the additional 40% discount to the sale price to find the final price:
Final price = Sale price - (40% of sale price) = $78 - ($78 imes 0.40) = $78 - $31.20 = $46.80
Therefore, the final price of the dress after the 40% discount is $46.80.
