Accepted Solution

A:
Answer: There are approximately 191 people that do not have a briefcase.Step-by-step explanation:Since we have given that 8 out of 11 people are carrying a briefcase.Then fraction of people carrying a  briefcase = [tex]\dfrac{8}{11}[/tex]Fraction of people do not have a briefcase = [tex]1-\dfrac{8}{11}=\dfrac{11-8}{11}=\dfrac{3}{11}[/tex]Similarly, if there are 700 people on a subway, then we will  find the number of  people do not having a briefcase.Since there is a direct variation,[tex]\dfrac{3}{11}=\dfrac{x}{700}\\\\\\x=\dfrac{700\times 3}{11}\\\\\\x=190.90\\\\\\x\approx 191[/tex]Hence, there are approximately 191 people that do not have a briefcase.
