The arithmetic, line by line
| Step | Calculation | Result |
|---|---|---|
| Discount rate as a decimal | 40 ÷ 100 | 0.40 |
| Discount amount | $149.99 × 0.40 | $60.00 |
| Final price | $149.99 − $60.00 | $89.99 |
| Price paid, share of original | $89.99 ÷ $149.99 × 100 | 60% |
At $1.50 per percentage point, the 10-point move up to 50% changes the saving by $15.00 on a single unit. Two units bought at 40% save $120.00 between them, which is $45.00 more than one unit at 50% ($75.00) — quantity and discount rate are separate levers and they do not trade evenly.

$89.99. The discount is 40% of $149.99, which is $60.00, and that comes straight off the price: $149.99 − $60.00 = $89.99.
How much do I save at 40% off $149.99?
$60.00 on a $149.99 item, which is the 40% that comes off before the till total of $89.99. The share you still pay is 60%, and sales tax is charged on that smaller figure rather than on the original.
Is 40% off plus another 40% off the same as 80% off?
No. Stacked percentages multiply, so 40% then 40% is 64% off in total, not 80%. On $149.99 the first cut leaves $89.99, and a second 40% takes it to $54.00.
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 $97.19 on a $89.99 subtotal, not 8% of $149.99. There are exceptions for manufacturer coupons and mail-in rebates, but a shelf discount is applied first.
