Attendance at a library for Saturday and Sunday combined was 50% of the average attendance for the preceding 5 days. The weekend's attendance was approximately what percentage of the attendance for the entire 7-day period?
A. 9%
B. 11%
C. 15%
D. 30%
E. 33%
The easiest way to go about answering the question is picking number.
Assume the average attendance of the week to be 50, meaning that
each day of the week, the library had an attendance of 50. Since, the
attendance of the weekend combined was 50% of the preceeding 5
days, it must be 25.
Total attendance in a 7 year period is \(50*5 + 25 = 275\)
27.5 will be 10%, so 25 should be less than 10%, the only answer option is
(Option A- 9%)
