Consumer Advocate: Happy Smiles Daycare, a popular child-care facility in Rolling Hills, boasts an average child-to-caregiver ratio of 5: 1, a number it cites as the lowest in the county. Furthermore, the daycare claims that compared to some other daycare centers in the county, it doesn’t include helpers, or those who are involved in cleanup and diaper changing, when computing the ratio. Yet Happy Smiles Daycare’s claim that parents with children aged 1– 3 will find no other facility with such a low child-to-caregiver ratio isn’t accurate.
Which of the following, if true, provides the best justification for the Consumer Advocate’s position?
A. Happy Smiles Daycare has two rooms, one for children 1– 2 years old and another for those 2– 3 years old, both of which have a child-to-caregiver ratio of 5: 1.
B. Kenton School, which has fewer than 100 students and a legitimate child-to-caregiver ratio of 6: 1, provides classes for each year up to age 6, though the classes for those over 3 years old have a child-to-caregiver ratio more than three times that of the other classes.
C. The number of students enrolled in Happy Smiles Daycare remains relatively fixed throughout the year.
D. Tiny Tots Daycare, which boasts a 4: 1 child-to-caregiver ratio, includes any adults who are in a classroom throughout the day.
E. Looming budget cuts indicate that Happy Smiles Daycare may not be able to sustain such a low child-to-caregiver ratio in coming years.
The question is testing averages.
HSD claims 5:1 ratio of children:caregiver.
The author says that HSD's claim of "lowest" ratio of 5:1 for 1 - 3 olds is not accurate.
Why? Option B tells us that Kenton has an average ratio of 6:1 for all its 1 - 6 year olds but its ratio for 4 - 6 year olds is actually 18:1. This means its ratio for 1-3 year olds is much lower than 6:1 and could easily be 4:1 or 3:1 etc. So Kenton could easily have a ratio lower than 5:1 and hence HSD may not hav the lowest ratio.
