Forward: $49.99 item at 8.5% sales tax. Tax = $49.99 × 0.085 = $4.25. Total = $49.99 + $4.25 = $54.24. Reverse: Total $54.24, rate 8.5%. Pre-tax = $54.24 ÷ 1.085 = $49.99. Tax = $54.24 - $49.99 = $4.25. Common mistake: $54.24 × 0.085 = $4.61 (WRONG — this is 8.5% of the total, not the original price). Always divide by (1 + rate) when working backwards.
