1. Stating the problem: A pair of pants originally cost 600 and now costs 550 during a sale. We need to find the percent decrease in price. 2. Calculate the decrease in price: $$\text{Decrease} = 600 - 550 = 50$$ 3. Calculate the percent decrease: $$\text{Percent decrease} = \frac{\text{Decrease}}{\text{Original Price}} \times 100\% = \frac{50}{600} \times 100\%$$ 4. Simplify the fraction: $$\frac{50}{600} = \frac{5}{60} = \frac{1}{12} \approx 0.0833$$ 5. Multiply by 100% to get the percent: $$0.0833 \times 100\% = 8.33\%$$ 6. Final answer: The percent decrease in price is 8.33%.
