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

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 2

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 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%.
