How We Calculated This
90% off $40 means you pay 10% of the original price.
$40 × 0.10 = $4.00
The discount amount is $40 × 0.90 = $36.00, which gets subtracted from the original $40 price.
Rule of 100: For items under $100, percentages sound bigger. "90% off" feels more impressive than "$36.00 off" — even though they’re identical.
