Question

If you are calculating a 15% discount what do you need to do to know the sale price

Answer 1

To calculate the sale price after applying a 15% discount, you can follow these steps:

1. **Determine the original price of the item.**
- Let's call this amount \( P \).

2. **Calculate the discount amount.**
- Multiply the original price by the discount percentage (expressed as a decimal):
\[
\text{Discount amount} = P \times 0.15
\]

3. **Subtract the discount amount from the original price to find the sale price.**
\[
\text{Sale Price} = P - \text{Discount amount}
\]
\[
\text{Sale Price} = P - (P \times 0.15)
\]
\[
\text{Sale Price} = P \times (1 - 0.15)
\]
\[
\text{Sale Price} = P \times 0.85
\]

So, to find the sale price after a 15% discount, you can simply multiply the original price by 0.85.
