The arithmetic, line by line
| Step | Calculation | Result |
|---|---|---|
| Discount rate as a decimal | 20 ÷ 100 | 0.20 |
| Discount amount | $34.99 × 0.20 | $7.00 |
| Final price | $34.99 − $7.00 | $27.99 |
| Price paid, share of original | $27.99 ÷ $34.99 × 100 | 80% |
At $0.35 per percentage point, the 5-point move up to 25% changes the saving by $1.75 on a single unit. Two units bought at 20% save $14.00 between them, which is $5.25 more than one unit at 25% ($8.75) — quantity and discount rate are separate levers and they do not trade evenly.

$27.99. The discount is 20% of $34.99, which is $7.00, and that comes straight off the price: $34.99 − $7.00 = $27.99.
How much do I save at 20% off $34.99?
$7.00 on a $34.99 item, which is the 20% that comes off before the till total of $27.99. The share you still pay is 80%, and sales tax is charged on that smaller figure rather than on the original.
Is 20% off plus another 20% off the same as 40% off?
No. Stacked percentages multiply, so 20% then 20% is 36% off in total, not 40%. On $34.99 the first cut leaves $27.99, and a second 20% takes it to $22.39.
Does sales tax apply before or after the discount?
After, in every US state that taxes the sale. Tax is charged on what you actually pay, so at 8% you owe $30.23 on a $27.99 subtotal, not 8% of $34.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
