Question

calculate total cost after discount

Answer 1

To calculate the total cost after a discount, you can follow these steps:

1. **Determine the original price** of the item or service.
2. **Find the discount rate** (as a percentage).
3. **Calculate the discount amount** by multiplying the original price by the discount rate (in decimal form).
4. **Subtract the discount amount** from the original price to get the total cost after the discount.

Here's the formula:

\[ \text{Total Cost After Discount} = \text{Original Price} - \left(\text{Original Price} \times \frac{\text{Discount Rate}}{100}\right) \]

### Example:

- **Original Price**: $100
- **Discount Rate**: 20%

1. **Calculate the discount amount**:
\[
\text{Discount Amount} = 100 \times \frac{20}{100} = 20
\]

2. **Calculate the total cost after discount**:
\[
\text{Total Cost After Discount} = 100 - 20 = 80
\]

So, the total cost after the 20% discount would be $80.
