A $72 item is 25% off
- Savings = 0.25 × 72 = $18.
- Sale price = 72 − 18 = $54.
- Check: 0.75 × 72 = $54.
Discounts & sale prices
Separate the money saved from the money paid.
A discount is the amount removed
For a regular price P and discount d%, savings = P × d/100. Sale price = P − savings. An equivalent method is sale price = P × (1 − d/100). The multiplier represents the share of the original price you still pay.
Separate saved from paid.
Predict first. Change one value, then explain what stays the same and what changes. All bars use the same scale within a model.
Read the coupon conditions
Check whether a coupon applies to one item, selected items, or the basket total. A $5 coupon removes a fixed dollar amount; a 5% coupon removes a share of the eligible price. Minimum purchases and limits affect which coupon is better. A price floor at zero means an unused discount is not automatically cash back.
Make an estimate and label your receipt
Record original price, savings and sale price separately. If the discount is 25%, you still pay 75%. Half off should halve a price; a small discount should not reduce it nearly to zero. Follow the stated rounding convention and keep each coupon step visible.
Worked examples
Compare $6 off with 15% off a $32 item
- 15% × $32 = $4.80 saved; pay $27.20.
- $6 off gives a $26 sale price.
- The fixed coupon saves $1.20 more for this eligible item.
Guided Practice
A $45 item has 20% off. Find both the saving and sale price.
A first hint
You pay 80% of the original price.
Compare your reasoning
Savings = 0.20 × 45 = $9. Sale price = $36.

Record the whole, the percent multiplier and the result with units. For each coupon, use the eligible amount at that step. State whether a resale percentage means percent of cost or markup on cost.
