The listed price of a dress is $59.99. If the tax is 8%, what is the total cost?

To determine the total cost of the dress, including tax, you first calculate the amount of tax applied to the listed price. The listed price is $59.99, and the tax rate is 8%, which can be expressed as 0.08 in decimal form.

First, you calculate the tax amount: Tax amount = Listed price × Tax rate

Tax amount = $59.99 × 0.08 = $4.7992

Next, you add the tax amount to the listed price to find the total cost: Total cost = Listed price + Tax amount Total cost = $59.99 + $4.7992 ≈ $64.7892

When rounding this figure to two decimal places, which is standard for currency, the total cost comes to $64.79.

Thus, the total cost of the dress after including the tax is $64.79. This calculation shows why the choice reflecting this total is the correct answer.
