To find the percent error, we need to compare the average number of tickets sold (1,200) to the actual number of tickets sold in each city.
For City A, the percent error is calculated as (actual number of tickets sold - average number of tickets sold) / average number of tickets sold * 100. So, for City A, the calculation is (1,100 - 1,200) / 1,200 * 100 = -0.083333333 * 100 = -8.33%.
For City B, the percent error is (1,000 - 1,200) / 1,200 * 100 = -0.166666667 * 100 = -16.67%.
For City C, the percent error is (950 - 1,200) / 1,200 * 100 = -0.208333333 * 100 = -20.83%.
Since we are asked to round to the nearest whole number, the percent errors for the three cities are:
City A: -8%
City B: -17%
City C: -21%
