Question

Answers:
30
39
50
70

Answer 1

39

Explanation:

The easy way to think about this is to think if it as 10%. You move the decimal one place to the left. so 130 becomes 13.0. if 10% of 130 is 13, what's 70%? multiply 13 by 7 And you get 91. that's not the answer. it's asking how many were NOT checked in for the flu, which is the other 30%. to get this, subtract the 91 (patients checked in for the flu) from 130 (total number of patients) and that gives you 39, the number of patients not checked in for the flu.
