The complement method involves subtracting each discount rate from 1 to find the complement (e.g., 1 - 0.15 = 0.85 for the first discount), then multiplying these complements together and finally by the original price to find the net price equivalent. Thus, (0.85 × 0.8 × 0.9) × price correctly applies this method.
