A day care worker found 28 children absent one day during an epidemic of chicken pox. If this was 35% of the total number of children attending the day care center, how many children attend this day care center?

80 children attend this day care,

Step-by-step explanation:

Let x represent the number of children that attend this day care center. The day care worker found 28 children absent one day during an epidemic of chicken pox.

If this was 35% of the total number of children attending the day care center, it means that the number of children absent one day during the epidemic of chicken pox can be expressed as

35/100 * x = 0 ... 35*x = 0.35x

Therefore,

0.35x = 28

x = 28/0.35 = 80
