Discounts & tax
Sale prices, discount amounts, sales-tax amounts and totals — including tax on the sale price.
Tips & change
Tip amounts and bill totals, percent increase and decrease (always change ÷ original).
Tricky combos
Successive percents, finding the original price, and simple interest.
3 Watch out for these
The three traps from the lesson, in one place.
Wrong: $50 → $65: 15/65 ≈ 23% Right: 15/50 = 30%. The original is the denominator.
Wrong: 8% tax on the $80 tag = $6.40 Right: 8% on the $60 sale price = $4.80.
Wrong: $100 → $70 → $100 Right: $100 → $70 → $91. Percents don’t undo.
