To find out how much Sally paid for the leather chair, including tax, we can follow these steps:
-
Calculate the markup price: The store marked up the original cost of the chair by 100%. Since the original cost is $494.47, the markup amount is the same as the original cost:
\[ \text{Markup} = 100% \times 494.47 = 494.47 \]
Therefore, the marked up price (selling price) is:
\[ \text{Selling Price} = \text{Original Cost} + \text{Markup} = 494.47 + 494.47 = 988.94 \]
-
Calculate the sales tax: The sales tax is 5.5% of the selling price. We can calculate this by multiplying the selling price by the sales tax rate:
\[ \text{Sales Tax} = 5.5% \times 988.94 = 0.055 \times 988.94 \approx 54.40 \]
-
Calculate the total amount paid by Sally: To find the total amount that Sally paid, we add the selling price and the sales tax together:
\[ \text{Total Amount} = \text{Selling Price} + \text{Sales Tax} = 988.94 + 54.40 \approx 1043.34 \]
Thus, the total amount Sally paid for the leather chair, including tax, is approximately $1043.34.
