The freshman class wants to include at least 120 people in the pep rally. Each skit will have 15 people and the dance routines will feature 12 people.
a) List two possible combinations of skits and dance routines.
b) Write an inequality to represent the situation.
a) Possible combination 1: 8 skits (15 people per skit) + 5 dance routines (12 people per routine) = 120 people
Possible combination 2: 4 skits (15 people per skit) + 10 dance routines (12 people per routine) = 120 people
b) Let S be the number of skits and D be the number of dance routines. The inequality to represent the situation is:
15S + 12D ≥ 120
