The ChildCare Center (CCC) is a medium-sized child care facility that offers daytime supervision
and instruction on weekdays (Monday through Friday) for children up to the age of 5. There are
many children who attend CCC every weekday, and a relatively small number attend fewer than
3 days per week.
The classroom assignment and daily fee paid to CCC for each child are determined by the
child's age on Friday of the previous week.
The ratio of the number of classroom staff in a particular classroom to the number of children in
that classroom is subject to local regulations—certain minimum staff-to-child ratios are to be
met or exceeded in every classroom. The minimum ratio for a particular classroom is
determined by the age of the youngest child in the classroom. The table shows these
minimums. Each day, CCC assigns to each classroom the least number of staff members
needed to comply with the local regulations.
The table shows the daily attendance at CCC for Week 2 of a recent fiscal year. The roster of
children attending CCC—as well as the days of the week each child attended—was unchanged
from Week 1 through Week 3.
From the Saturday before Week 2 through the Friday of Week 2, exactly eight of the children in
attendance at CCC had birthdays. Two children turned 1, one child turned 2, one child turned 3,
and four children turned 4. All changes to classroom attendance from Week 2 to Week 3 were
due to these birthdays.
For each of the following classrooms, select More staff if more classroom staff members were
assigned to that classroom on the Monday of Week 3 than on the Monday of Week 2.
Otherwise, select Same/fewer staff.
More staff Same/few staff
