80 students are scheduled to attend a field trip to a local fishery. A maximum of 16 students are allowed to tour the facility at one time. Write an inequality which describes how many tour groups, g, to organize.

Ok. You have to find the number of groups it'll take to have all of the students go through the fishery. The number of groups has to be equal or greater to the number of students, because you can't have a fraction of a group. (S = number of students)

16s≥80

since there are 80 students, you'll need 5 groups even.
