A pair of shoes usually sells for $55. If the shoes are 20% off, and sales tax is 6%, what is the total price of the shoes including tax?

To calculate the total price of the shoes including tax, we can follow these steps:

1. Calculate the discount. The shoes are originally priced at $55, and they are 20% off. \[ \text{Discount} = 55 \times 0.20 = 11 \]

2. Calculate the sale price after the discount. \[ \text{Sale Price} = 55 - 11 = 44 \]

3. Calculate the sales tax. The sales tax is 6% of the sale price. \[ \text{Sales Tax} = 44 \times 0.06 = 2.64 \]

4. Calculate the total price including tax. \[ \text{Total Price} = 44 + 2.64 = 46.64 \]

Therefore, the total price of the shoes including tax is $46.64.

The correct answer is B. $46.64.
