If there are [tex]n[/tex] groups of people, each consisting of 4 people, then there is a total of [tex]4n[/tex] people. Including the 8 employees, you have a grand total of [tex]4n+8[/tex] people attending the screening. There has to be less than 80 people allowed in, so the appropriate inequality would be
[tex]4n+8<80[/tex]
