Question

An item is regularly priced at $15. Shen bought it on sale for 20% off the regular price. How much did Shen pay?

Answer 1

An item costs $340 before tax, and the sales tax is $ 10.20.
Find the sales tax rate. Write your answer as a percentage.

Answer 2

To find out how much Shen paid after the discount, first, we need to calculate the amount of the discount.

1. Calculate the discount:
\[
\text{Discount} = \text{Regular Price} \times \text{Discount Rate}
\]
\[
\text{Discount} = 15 \times 0.20 = 3
\]

2. Now, subtract the discount from the regular price to find the sale price:
\[
\text{Sale Price} = \text{Regular Price} - \text{Discount}
\]
\[
\text{Sale Price} = 15 - 3 = 12
\]

Thus, Shen paid **$12** for the item.

Answer 3

To find the sales tax rate, we use the formula:

\[
\text{Sales Tax Rate} = \left( \frac{\text{Sales Tax}}{\text{Cost Before Tax}} \right) \times 100
\]

In this case, the cost before tax is $340 and the sales tax is $10.20.

1. Calculate the sales tax rate:
\[
\text{Sales Tax Rate} = \left( \frac{10.20}{340} \right) \times 100
\]

2. Performing the division:
\[
\frac{10.20}{340} \approx 0.030
\]

3. Now, multiply by 100 to convert it to a percentage:
\[
0.030 \times 100 = 3.0\%
\]

Therefore, the sales tax rate is **3.0%**.
