B Correct answer
Explanation

Selling price = Marked Price * (1 - discount rate) = 150 * (1 - 0.21) = 150 * 0.79 = 118.5.

AI explanation

To find the final selling price, subtract the discount percentage from 100 to find the selling price percentage, which is 100 minus 21, giving 79%. Using the formula Selling Price equals Marked Price multiplied by Selling Price Percentage divided by 100, we calculate 150 times 79 divided by 100. This results in a final selling price of 118.5 dollars.
