The table shows the attendance at the art show for the past week. Art Show AttendanceDayAttendanceSunday54Monday29Tuesday22Wednesday28Thursday12Friday15Saturday?What does the attendance need to be on Saturday to have an average attendance for the week of 30 people per day?

An average of 30 people over 7 days requires a total attendance of 30 × 7 = 210. The six listed days add up to 54 + 29 + 22 + 28 + 12 + 15 = 160, so Saturday’s attendance must be 210 − 160 = 50 people. The correct choice is 50.
