We have to calculate the sales tax and total sales.
We know the item marked price ($594.47) and the sales tax rate (4.874%).
We can start by calculating the sales tax as the item marked price times the sales tax rate (expressed in decimal form):
![\begin{gathered} ST=MP\cdot r \\ ST=594.47\cdot(4.874)/(100) \\ ST=594.47\cdot0.04874 \\ ST\approx28.97 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/2r3mmsnzthp9a71n44j4oc5cxl7gcjsmua.png)
We now can calculate the total sales as the sum of the item marked price and the sales tax:
![\begin{gathered} TS=MP+ST \\ TS=594.47+28.97 \\ TS=623.44 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/ofrmroqd49zisqtv7pg8wlr64zxumrsaex.png)
Answer:
Sales tax = $28.97
Total sales = $623.44
