A sweater originally priced at $80 was discounted by 25%. Later, its price was increased by 10% of the discounted price. What is the final price of the sweater?

✓ Correct Answer: Option B

First, the discounted price: $80 * (1 - 0.25) = $80 * 0.75 = $60. Then, the price was increased by 10% of the discounted price: $60 * (1 + 0.10) = $60 * 1.10 = $66. The final price is $66.
