STEP 1

Assumptions1. The cost of the item before tax is $480. The sales tax on the item is$43.203. The sales tax rate is calculated as a percentage of the cost of the item before tax

STEP 2

We can find the sales tax rate by dividing the sales tax by the cost of the item before tax and then multiplying by100 to convert it to a percentage.
$$Sales\, tax\, rate = \left(\frac{Sales\, tax}{Cost\, before\, tax}\right) \times100\%$$

STEP 3

Now, plug in the given values for the sales tax and the cost before tax to calculate the sales tax rate.
Sales\, tax\, rate = \left(\frac{\($\)43.20}{\($\)480}\right) \times100\%

STEP 4

Perform the division to find the decimal value of the sales tax rate.
$$Sales\, tax\, rate =0.09 \times100\%$$

Finally, multiply the decimal value by100 to find the sales tax rate as a percentage.
$$Sales\, tax\, rate =0.09 \times100\% =9\%$$The sales tax rate is9%.
