Problem
The attendance at a high school homecoming game was 550 last year. Due to bad weather, the attendance at this year's homecoming game decreased by 11 people. What was the percent decrease? The attendance at the homecoming game decreased by \( \% \).
Solution
Step 1 ：\text{Initial Attendance: }550
Step 2 ：\text{Decreased Attendance: }550 - 11 = 539
Step 3 ：\text{Percentage Decrease: }\frac{550 - 539}{550} \times 100 = \frac{11}{550} \times 100
