An item is regularly priced at $45. It is on sale for 20% off the regular price. How much (in dollars) is discounted from the regular price?Amountdiscounted:$

1. ### Break Down the Problem

To find the discounted amount from the regular price of the item, we need to calculate 20% of $45.

2. ### Relevant Concepts

The formula to calculate the discount is: $\text{Discount} = \text{Regular Price} \times \left(\frac{\text{Discount Rate}}{100}\right)$ Where:

• Regular Price = $45
• Discount Rate = 20%

3. ### Analysis and Detail

Using the formula, we can substitute in the values: $\text{Discount} = 45 \times \left(\frac{20}{100}\right)$

Calculating the discount step by step: $= 45 \times 0.20$ $= 9$

4. ### Verify and Summarize

We can verify the calculation as follows. If the regular price is $45 and the discount is$9, then the sale price would be: $\text{Sale Price} = \text{Regular Price} - \text{Discount}$ $= 45 - 9$ $= 36$ This confirms that the calculations align well for the sale price.

Final Answer

The amount discounted from the regular price is $9.
